Small Victories

Written by : Robert C. Cooper
Directed by : Martin Wood

Episode Guide : 401
Guest Stars : Colin Cunningham as Major Davis and Gary Jones as Technician


Synopsis : SG-1 returns the SGC with news that earth has been saved from the replicators only to learn that one of the deadly creatures was not destroyed. After crashing into the ocean aboard Thor's ship, the replicator bug has found its way into a Russian submarine where it has killed the entire crew and is continuing to rapidly replicate. O'Neill suggests that the sub be towed out to sea and nuked, but the Pentagon feels that such an act could cause a serious situation with the Russian government. Instead, O'Neill and Teal'c lead a small heavily armed team aboard the sub in the hopes that the replicators can be eliminated by sheer firepower. Carter is taken to Thor's home planet which is on the verge of total destruction by the replicators. Thor believes that perhaps Carter's human knowledge could hold the key to the Asgard defeating the replicators once and for all.

Guest Stars : Rene Auberjonois as Alar and Anne Marie Loder as Farrell


Synopsis : The SGC is contacted by Alar, a representative of the planet Euronda. His people, who claim direct descent from Earth, are under attack and in need of help. General Hammond sends SG-1 on a humanitarian mission to deliver food and medical supplies. SG-1 arrives to find a civilization devastated by war - and a leader desperate to make a deal. In exchange for the heavy water they need to sustain their defensive fields, Alar is prepared to offer advanced Eurondan technology. O'Neill quickly agrees to the trade. Daniel, however, is suspicious that the Eurondans have not been completely honest about their agenda and sets out to discover the truth.


Upgrades

Episode Guide : 403
Guest Stars : Vanessa Angel as Anise


Synopsis : Anise, a new Tok'ra representative to Earth, approaches the SGC for help in testing some mysterious armband devices discovered amongst the ruins of a distant planet. Anise believes the devices could prove a powerful weapon in their war against the Goa'uld. However, since symbiotes seem to render the devices ineffective, she requires human test subjects to prove her theory. O'Neill, Carter, and Daniel volunteer. They are outfitted with armbands and within a short time, begin to demonstrate incredible strength and speed. But Dr. Fraiser grows concerned when medical tests suggest that the devices could be endangering their lives. General Hammond orders the armbands removed - only SG-1 is shocked to discover the devices will not come off. Anise sees an opportunity and suggests that SG-1, now outfitted with the armbands, be sent to destroy a new ship being built by Apophis. The General flatly refuses and orders SG-1 to remain on base. Their judgment clouded by the alien devices, the team defies the order and sets off on what could well be a suicide mission.

Crossroads


Written by : Kathryn Powers
Directed by : Peter DeLuise

Episode Guide : 404
Guest Stars : Vanessa Angel as Anise, Musetta Vander as Shan'auc, Peter Wingfield as Hebron, and Gary Jones as Technician


Synopsis : SG-1 responds to an incoming wormhole with Bra'tac's signal. Instead of Bra'tac, they find Shan'auc who tells them that she has come on behalf of Bra'tac. Teal'c goes to Shan'auc and it is immediately evident to all that the two share chemistry and history. Shan'auc claims to have discovered a way to communicate with her symbiote, and it, in turn, has shared memories with her. These memories, she believes, could be the means to defeat the Goa'uld. She claims that through their communications, she has convinced her symbiote that the Goa'uld are evil. The symbiote is prepared to tell all it knows to the Tok'ra. Teal'c remains skeptical of Shan'auc's claim, until he, himself, shares a memory with his symbiote. The Tok'ra agree that Sha'auc's symbiote is of great value and find a willing Tok'ra host for it. Will the symbiote continue to tell its secrets and offer a method to defeat the Goa'uld or has it cleverly deceived Sha'auc, SG-1 and the Tok'ra?

Divide And Conquer

Written by : Tor Alexander Valenza

Episode Guide : 405
Guest Stars : Vanessa Angel as Anise, J.R. Bourne as Martouf, and Kirsten Robek as Lt. Astor


Synopsis : During a meeting with the Tok'ra high council, Major Graham of the SGC goes berserk, firing uncontrollably upon the Tok'ra before taking his own life. The SGC is stunned to discover that Graham is a Zatarc, the victim of Goa'uld mind control technology. According to Anise, its victims are subconsciously programmed to kill, their recollection of the procedure covered by false memories. Anyone who has come into contact with the Goa'uld could well be a Zatarc - and wholly unaware of the fact. Through the use of an experimental testing device designed by the Tok'ra, Anise sets out to determine who, at the SGC, has been programmed. The test proves successful in uncovering a second Zatarc - Lieutenant Astor, a former teammate of Graham's, who also goes berserk, shooting up the SGC before turning the gun on herself. But subsequent testing uncovers false memories in two more members of the SGC: Colonel Jack O'Neill and Major Samantha Carter.

Directed by : Peter DeLuise

Episode Guide : 406
Guest Stars : Robin Mossley as Malikai


Synopsis : While exploring planet P4X 639, the SG-1 team meets Malikai, a human explorer from another world who shares Daniel's interest in an alien computer covered in a strange Latin-like script. As solar flares flash from the red sun overhead, Malikai warns Daniel that the geomagnetic disturbance may be dangerous to the SG-1 team and tells him to leave. When Daniel ignores him, Malikai zaps him with a weapon and begins to program the alien computer. O'Neill and Teal'c rush to Daniel's aid and are caught, with Malikai, in a mysterious blue light. Suddenly, they find themselves back at Stargate command, ten hours earlier, preparing to head off on the mission they've just returned from. And then it happens again. And again. And again. As O'Neill returns to eat the same plate of Fruit Loops over and over again, it becomes clear that they've been caught in a time loop and that only he and Teal'c retain their memories through each ten-hour cycle. It's up to them to decode the message on the mysterious machine and figure out a way to break the loop.

Watergate

Written by : Martin Wood
Directed by : Robert Cooper

Episode Guide : 407
Guest Stars : Marina Sirtis as Svetlana and Gary Jones as Technician


Synopsis : When the Stargate won't open, trapping teams offworld, the SG-1 team investigates and learns that the Russians have their own Stargate. Their Stargate, apparently recovered from the sea after an Asguard ship crashed on earth, is locked open, maintaining a perpetual wormhole that defies explanation. At the request of Russian scientist Dr. Svetlana Markov, the SG-1 team is dispatched to the Russian stargate facility, where they make a shocking discovery. All the soldiers and scientists are dead and the Stargate remains locked open, connected to a water-covered planet. Svetlana explains that the Russians had retrieved a sample of the water, and found it has amazing properties, including the ability to emit significant levels of energy. That same water, however, seems to have disabled the drone, leaving it inoperable and sending transmissions that are keeping the gate open. Daniel, Carter and Svetlana head through the wormhole in a miniature submarine in an attempt to recover the drone. The water brings the sub to a halt and begins to crush it, leaving the team unable to return through the Stargate. Meanwhile, back at the Russian facility, O'Neill and Teal'c make their own shocking discovery. Inside a freezer is the frozen body of Col. Maybourne, a SG-1 turncoat who has apparently been advising the Russians. As he begins to thaw, he comes back to life, spewing out gallons of water and a terrified warning. This may look like H20, but it's alive and it's playing for keeps.

The First Ones

Directed by : Peter DeLuise

Episode Guide : 408
Guest Stars : Gary Jones as Technician and Dion Johnstone as Chaka Unas


Synopsis : While conducting an archeological dig on planet P3X 888, Daniel Jackson makes a remarkable discovery: a primordial Goa'uld symbiote, an ancient, predatory version of SG1's parasitical enemies. Before he can bring back his sample however, his team is attacked by an Unas. One team member is killed and Daniel is dragged off into the wilderness by the giant primitive creature. Learning of Daniel's disappearance, O'Neill leads a rescue mission to the planet. Upon his arrival, he discovers that SG-11 has been almost wiped out - only Hawkins survived - and the planet's water supply is teeming with Goa'uld symbiotes. While O'Neill and Teal'c struggle with the possibility that one of their men may have been inhabited by a Goa'uld, Daniel is dragged further into the wilderness by his captor. Gradually, he begins to understand a few words of the creature's language. The Unas, a juvenile whose name seems to be Chaka, saves Daniel's life when he's attacked by a symbiote. As the rescue team struggles to catch up, however, the question remains: has Daniel become the Unas' newest friend or is he simply being brought home for dinner?

Scorched Earth

Written by : P. Mullie and Joseph Mallozzi
Directed by : Martin Wood

Episode Guide : 409
Guest Stars : Brian Markinson as Lotan and Marilyn Norry as Hedrazar


Synopsis : Thanks to SG-1, a civilization known as the Enkarans have been transplanted from a Goa'uld slave planet to a safer, more hospitable world. But soon after they settle in, problems arise. One of their villages is attacked by a mysterious ship. The Enkarans seem to be facing a threat even more formidable than the Goa'uld. But when SG-1 investigates, they discover that the mystery ship has no hostile intent. It is merely terraforming the planet in order to make it habitable for the Gadmeer, a long-dormant alien species. Lotan, a bio-mechanical liaison created by the ship, explains that once the terraforming procedure has begun, it cannot be halted. To do so would mean extinction for the Gadmeer. On the other hand, a completion of the terraforming process would mean certain death for the Enkarans. SG-1 must find a solution to this ethical dilemma, or face the extinction of an entire race.

Synopsis : SG-1 awakens in a mysterious underground complex with no memory of their previous lives. In fact, they seem to possess a whole new set of memories. No longer O'Neill, Carter, Daniel, and Teal'c, they are Jonah, Therra, Carlin and Tor, laborers doomed to a dreary existence, working the mines beneath an ice-covered planet. Back at the SGC, meanwhile, General Hammond is faced with the possibility that SG-1 perished on the planet's icy surface, a possibility he refuses to accept. As the General tries to unravel the team's mysterious disappearance, the members of SG-1 grasp at fleeting memories of their former lives, memories which are not just the keys to their freedom, but to their very survival.

Synopsis : The SGC is contacted by a rambling individual who claims full knowledge of a host of government conspiracies, from the Kennedy cover-up to CIA-sanctioned microwave harassment of Libertarian candidates. He sounds like a crackpot, someone hardly worthy of their attention, that is until he mentions the Stargate. Hammond wants to play it safe. They need to check this guy out.

O'Neill meets with the mystery caller, a nebbish fellow named Martin Lloyd who insists he is an alien and in possession of a space ship (who's location slips his mind at the moment).

Shifu is brought back to Stargate Command where he undergoes a series of tests. They reveal Shifu is physically normal. But it is apparent to all that the young boy is wise beyond his years. Possessing the genetic memory of the Goa'uld, he will undoubtedly prove a powerful weapon against the System Lords.

Faced with this prospect, the Harsesis child sets out to teach Daniel a lesson - by imbuing him with the sought-after genetic memories and launching him on a spiritual journey.

O'Neill, Carter, and Teal'c check out the site and discover a room with a mesmerizing light display. They conclude that the temple was, at one point, a Goa'uld pleasure palace. As their investigation progresses, they come to realize that the temple is directly affecting their brain physiology - delivering euphoric highs while they are on its premises, and debilitating lows of withdrawal when they attempt to leave. Trapped, they must find a way to break this otherworldly addiction.

As it turns out, a young man, seemingly unaffected by the strange environment, may hold the key to their salvation.

SG-1 is prepared to lead them once again, but it turns out their former allies are not so eager to answer the call to arms. After all, they were promised that if they buried their gate, they would be safe. Instead, the Goa'uld returned in ships - and the planet's inhabitants paid a terrible price.

Exodus

Written by : Paul Mullie and Joseph Mallozzi
Directed by : David Warry-Smith

Episode Guide : 421
Guest Stars : Carmen Argenziano as Jacob Carter/Selmak and Peter Wingfield as Tanith


Synopsis : SG-1 pays a visit to the Tok'ra homeworld. They arrive at Vorash on Cronos's mother ship, one of the spoils they claimed following the events of "Double Jeopardy". At a meeting with the High Council, it is revealed that SG-1 intends to lend the Tok'ra the enormous ship in order to help facilitate their move to a new planet. Tanith is beside himself. Why wasn't he made aware of this plan? Teal'c informs him that he could not be trusted because he is, after all, a spy for Apophis. The Tok'ra have known all along. An enraged Tanith is taken away.

The Tok'ra begin to move items up to the mother ship. Preparations are underway for the extraction ceremony that will remove Tanith from his host. But amidst all the activity, Tanith escapes his cell and flees up to the planet's desert surface.

A search operation is mounted, but no trace of the Goa'uld is found. Then, the Tok'ra receive word. Tanith must have gotten a message out to Apophis. The System Lord has assembled his fleet and is headed for Vorash.

Carter and Jacob come up with a plan that, if successful, could deal Apophis a crippling blow. They will gate the Tok'ra to another planet, then load the stargate onto the ship and leave Vorash. Once in position, they will dial the address of the black hole planet, then jettison the gate into the sun. Given proper timing, this will cause the sun to go nova and destroy Apophis's fleet.

Everything goes according to plan. They launch the gate and prepare to flee. Suddenly, a Goa'uld ship decloaks and fires, crippling them.

Their weapons systems are down. Their hyperdrive is inoperative. And Apophis is closing fast. But, perhaps more importantly, the countdown has already begun on a blast that will take out the entire
