Stargate SG-1

While Sam and Teal'c go to the planet of the former human-form Replicators to contact the Asgard to cure Jack, Daniel and Dr. Weir must deal with Goa'uld System Lords who wish the Ancients weapon they used to destroy Anubis.

As the Replicators overwhelm the new Asgard homeworld, SG-1 works to revive Jack, create an Ancients weapon to stop the invaders, and tries to find the missing Sam, who is held captive by the human form Replicator Fifth in a virtual reality.

A Russian Air Force Colonel comes to join SGC, as an alien creature up at the same time. The creature starts taking over members of the SGC. General O'Neill orders SGC to be locked down until the creature can be contained.

Five days in the life of SGC as Jack assumes full command of the base and has to deal with a rapidly growing alien plant, the capture of SG1 by Ba'al, arguing alien delegates, and a tricky traitorous System Lord.

Daniel attempts to aid a battle-ravaged society when the team's appearance sparks a war.

The SGC experiment with a virtual reality chair from the Gamekeeper's world, but Teal'c becomes trapped in a virtual loop against an undefeatable batch of Anubis drones.

Teal'c moves into an apartment off-base where he becomes involved in a neighbor's problems. Meanwhile, Carter's boyfriend, Peter Shanahan, proposes and Carter tries to decide. Teal'c is then charged for murder and kidnapping. Daniel disappears while trying to prove Teal'c innocent.

A rich industrialist has evidence to prove that there is alien life on other planets and gives the governments of the world 24 hours to reveal the truth or he's revealing it. The Air Force tries to discredit him. Then Carter is given the job to tell him about the Stargate and the Goa'uld to try to convince him that the world doesn't need to know. The Trust also tries to silence him.

On the eve of his son's wedding, Teal'c is caught in the midst of a Jaffa uprising after Ishta (Jolene Blalock) is taken hostage by Moloc, the Goa'uld behind the rebellion.

The theft of the Stargate leads to SG-1's encounter with a devious cabal seeking to add the alien technology to its arsenal as assassins stalk the Jaffa.

Amanda Tapping has a dual role when Carter's Replicator clone seeks SG-1's help in thwarting the Fifth (Patrick Currie), who has discovered a method of nullifying the Asgard's latest weapon.

Daniel tries to persuade the survivor (Claudia Black) of a Gou'ald bloodbath to release the Prometheus, which she hijacked as part of a mission to find a home for her people.

Wayne Brady guest stars as the leader of a Goa'uld invasion force when SG-1 comes to the aid of a threatened civilization ruled by Earth's own Harry Maybourne (Tom McBeath).

Cold War tensions resurface when the Russians suspect aliens have infiltrated the U.S. government. Their evidence: a compromising video of Kinsey (Ronny Cox).

A troubled barber (Dan Castellaneta) threatens to bleed O'Neill white unless the Stargate commander publicly acknowledges the existence of the portal and SG-1.

Part 1 of two. As Jaffa resistance forces gather for an all-out assault to retake the holy city of Ta'kara, the system lord Baal (Cliff Simon) warns SG-1 about the return of a mutual foe.

Conclusion. SG-1 searches for the only weapon that can stop the Replicators as the battle against the Goa'uld escalates.

Hovering between life and death, Daniel mulls returning to an ascended state after encountering Oma Desala (Mel Harris) at a celestial diner. Meanwhile, Carter introduces her fiancé (David DeLuise) to her dad; Teal'c and Bra'tak are honored by a Jaffa priest (Isaac Hayes); and O'Neill hits it off with a sexy CIA agent (Clare Carey).

The SG-1 team journeys in time for a daring mission to obtain a piece of Ancient technology from the Pharaoh Ra - the Goa'uld from the 1994 film that inspired the series.

Conclusion. After SG-1's journey to ancient Egypt causes a hitch in time, leaving the team stranded, their alternate-timeline counterparts mount a rescue attempt.
