In alternate-reality present, Daniel's translation and Carter's scientific input prove vital, Jack's personal bond with major Kawalski allows Hammond to recruit him to command an alternate SG-1, minus alien, who agrees to take them along on a mission back in time to fix the past to save the future. In the process, the team lands on Chulack, where they are surprise-captured and incarcerated by Jaffa. They must convince and re-recruit Teal'c and escape to Gizeh. There they find the real Daniel Jackson, who has been preparing the uprising against Ra with local leader Katep, who hides them and the (painstakingly cloaked) time-machine from Ra's guard, while Daniel and Teal'c mastermind an amended uprising to leave ancient Egypt as due when they return. Alternate-time-line O'Neill and Carter express their love.
