While testing the new McKay-Carter intergalactic gate bridge, the Daedalus detects an Ancient Atlantian warship, traveling at just below light speed and heading towards Earth. Damaged in battle during the war with the Wraith, the Ancients aboard this ship fled the Pegasus galaxy and have spent thousands of years in stasis. Back on Atlantis, the now awoken Ancients meet with General O'Neill (Richard Dean Anderson) and Richard Woolsey (Robert Picardo). They thank the Stargate team for taking care of the city in their absence, but ask them to vacate Atlantis immediately. While Ronon and Teyla stay in the Pegasus galaxy, the remaining team members struggle to resume their lives on Earth. Sheppard (Joe Flannigan) doesn't gel with his new SG team, McKay (David Hewlett) is bored in his Area 51 lab, and Weir (Torri Higginson) has trouble finding meaning in a life after Atlantis. However, the SGC soon learns that the Replicators have overtaken Atlantis, as McKay had previously enabled the Replicators to re-write

In this sixth season premiere, Jonas (Corin Nemec), unable to return to Kelowna, is eager to "finish what the missing Dr. Jackson started." He and O'Neill (Richard Dean Anderson) are introduced to the X-302, the first human-built spacecraft capable of interstellar travel. Meanwhile, the Stargate mysteriously malfunctions and Carter (Amanda Tapping) informs O'Neill that it could explode and destroy all life on Earth. "Redemption, Pt. 1" ends with the fate of Earth in SG-1's hands and no apparent way to avert the impending catastrophe.

Carter (Amanda Tapping) estimates that the Stargate can only withstand the attack for another 54 hours. Teal'c (Christopher Judge) and his son, Ryac, decide to seek out and destroy the weapon that has transformed the gate into a time bomb. Meanwhile, Jonas (Corin Nemec) saves the day by devising a plan to explode the Stargate seconds after O'Neill (Richard Dean Anderson) passes through the hyperspace window. SG-1 acquires a new Stargate from the Russians, trading plans for the ill-fated X-302. As a reward for helping save the planet, Jonas becomes a full-fledged member of SG-1.

O Neill (Richard Dean Anderson) flees a Jaffa attack on an unknown planet but is captured alongside a slave before reaching the Stargate. Imprisoned and tortured by Ba'al the System Lord, O'Neill loses his memory and cannot remember where he is or why he is there. The specter of Daniel Jackson (Michael Shanks), who has been elevated to another plane of existence in death, appears in O'Neill's prison cell and offers the mystical wisdom of Oma. Since SG-1 lacks the firepower to attack Ba'al's fortress, Teal'c (Christopher Judge) suggests recruiting one of the other system lords to attack it. O'Neill and the slave escape together as Daniel appears one last time to tell him "You're going to be all right."

Martin Lloyd (Willie Garson), last seen in Wormhole X-treme, returns to the SGC looking for assistance from SG-1 with his feature film script. The team is reluctant, especially Lt. Colonel Cameron Mitchell (Ben Browder), who is excited about his next off-world mission, which marks his 200th trip through the event horizon. However, when technical glitches prevent the team from gating off-world, they are stuck in the boardroom under the orders of General Landry (Beau Bridges), because the Pentagon believes a successful science fiction film about intergalactic wormhole travel will serve as a good cover story to keep the Stargate Program a secret. The notes session, however, quickly devolves into the team members pitching their own versions of a successful sci-fi film - including tributes to The Wizard of Oz, Star Trek, a younger and edgier SG-1, and even a wedding that showcases the return of General Jack O'Neill (Richard Dean Anderson).

Ben talks about filling Richard Dean Anderson's shoes, the difference between Mitchell and Crichton, and his outlook on the future.

Television's most inventive and resourceful crime fighter is on the job as MacGyver launches its first season. A special operative for the Phoenix Foundation, a private think tank dedicated to fighting evil everywhere, MacGyver (Richard Dean Anderson) is sent out on missions ranging from rescue to seek and destroy -- but never without his trusty roll of duct tape and his all-purpose Swiss Army Knife. Disdaining violence and brute force, our hero wriggles out of his various perils by improvising weapons and such out of simple household devices at hand, from a light bulb to a credit card. This talent comes in handy in his first assignment, in which he goes to rescue a pilot whose plane has crashed atop a cliff. In subsequent episodes, MacGyver will use a magnet to recover stolen secret documents in Burma; escape from certain death in the desert by employing a hot-air balloon; employ a can of gasoline to ward off killer ants in Brazil; utilize a jerry-built blowgun to neutralize a virtual army of hitmen and resc
