The episode was written by producer Robert C. Cooper, and directed by Martin Wood. "Redemption" is the first episode where actor Corin Nemec had main cast status, his character Jonas Quinn replacing Daniel Jackson (played by Michael Shanks) who died at the end of season 5. The episode also marks the second appearance of David Hewlett's character Rodney McKay, who later became a main character on Stargate Atlantis. "Redemption Part 2" was nominated for a Gemini Award in the category "Best Visual Effects".
Part 1
Major Carter invites Jonas Quinn, who left his home planet and has been living at Stargate Command (SGC) since Daniel Jackson's death ("Meridian"), to leave the base with SG-1. At Area 51, they see the newly built fighter jet X-302 for the first time, but O'Neill refuses to test-fly it (because of the X-301 incident in season 4's "Tangent"). Back at the SGC, O'Neill denies the proposal of General Hammond and Col. Chekov, who wants a Russian as the new fourth member of SG-1. Jonas admits to Carter that he wants to be a member of SG-1, and talks with Teal'c about O'Neill's mistrust in him. When Teal'c talks with his Colonel, O'Neill claims that Jonas is an alien.
Bra'tac arrives at the SGC and informs Teal'c that Drey'auc (Teal'c wife) is ill. By the time they have reached Chulak, Drey'auc has died. Teal'c's teenage son Rya'c wants to take revenge on Teal'c and starts to beat him down, but Bra'tac intervenes. Teal'c talks with Rya'c during Drey'auc burial, and Rya'c starts to cry. Meanwhile, at Earth, the SGC Stargate was dialed from off-world and has stayed open beyond its 38-minute limit, with energy of the gate rapidly rising. Carter presumes that the gate will eventually explode and potentially cause the destruction of Earth. Dr. Rodney McKay arrives at the SGC as ordered much to Carter's annoyance. Carter informs Col. Chekov that the X-302 will soon be ready so that Earth can contact the Asgard for help. As O'Neill and Carter start with X-302, Jonas and McKay inform Hammond of potential problems with the X-302's hyperspace engine due to the instability of the naqahdriah. Shortly before the X-302 enters hyperspace, they miss the window and the mission is cancelled.
Back on Chulak, a Jaffa arrives with a Tel'tak and reveals that Anubis is going to attack Earth's Stargate. Through trial and error of dialing planets that belong to Anubis, they finally find out which world the weapon is on. Back at SGC, Carter can only assume what caused the problem. A hologram of Anubis appears in the gateroom, saying in a very dramatic way that they will all be destroyed soon, much to O'Neill's annoyance.
Part 2
Dr. McKay talks with Major Carter about the situation, when McKay has the idea of using an EMP. General Hammond allows him to proceed, despite Carter's protest. She also presents the problems with that plan, but Hammond orders her to work with McKay. The plan is finally carried out, but it doesn't work. Suddenly lightning strikes from the machine. When Carter closes the iris, she is struck down.
On the Jaffa world, they find out where Anubis has positioned the weapon and together with Rya'c they use a Tel'tak to go there. The planet is guarded by Ha'taks, who detect the cloaked cargo ship and thus Teal'c, Bra'tac and Rya'c ring down to the planet, where they attack the Jaffa. During the battle however Rya'c is wounded. They then hide because there are many guards and patrolling Death gliders. The three Jaffa then find the weapon (which is of Ancient origin) and while Rya'c has to stay hidden the two adults go to the weapon. However the weapon is protected by a force field.
At SGC, Carter's wounds are treated in the infirmary and she is visited by McKay who apologizes to her and tells her about his past. It is also revealed that the time until the explosion is cut in half, as Carter had predicted. Later Carter visits Jonas who looks at the Stargate and asks her how they got the Stargate in the gate room. This gives Carter an idea. She tells the scientists there to use the X-302 to fling the Stargate into space, and all of them start working. Hammond later talks with Colonel Chekov about the use of their Stargate, but the Russians demand a lot in return.
