On Juna, SG-1 gets a hostile welcome from the local warriors' leader Darian, who seems incredulous they even dared to return. They loyally deliver Sam and Teal'c to Cronus and told them to bury the Stargate. Cronus orders Darian to decapitate Daniel by staff weapon- to find his head is robotic. Cronus's obvious astonishment makes Darian doubt his divinity. At the SGC, Harlan urge them to go on a mission. The master robot-creator tells SG-1 that the robot versions of them he created need to recharge after 48 hours. In order to prevent the Goa'uld gaining access to their duplicates' memories, SG-1 reluctantly go to Juna. Darian now joins them, but feels most of his people won't dare challenge Cronus. The two Teal'cs concentrate on revenging the original's father by attacking Cronus recklessly, while the Sams and Jacks deal with the military problems and overthrowing the Goa'uld rule.

While still dealing with the loss of Daniel Jackson the SGC is contacted by the Asgard who require assistance dealing with Anubis, who seems to have new shield technology that can repel Asgard weapons.

Having obtained permission to live off the base, Teal'c rents an apartment, telling neighbors that he has recently arrived from Mozambique. He's under orders to keep a low profile but can't seem to help himself when it comes to helping his neighbors. He helps one who is about to be assaulted by three thugs, but it's his next-door neighbor who seems to need assistance. Krista is having problems with her boyfriend, Doug. Teal'c soon realizes that Doug is beating her and warns him that should he hurt her, Teal'c will kill him. It all becomes very difficult when Doug is found dead in Krista's apartment. Daniel Jackson soon after receives an offer - translate a Goa'uld text, and he will get ironclad evidence that Teal'c is innocent. Meanwhile, Carter is shocked when her boyfriend Pete Shanahan tells he asked for a transfer to the local police department and asks her to marry him.

Sam and Jacob are on the planet Dakara trying to configure the Ancient's device to destroy the Replicators once and for all, helped partly by Ba'al and Daniel, who succeeds in freezing the Replicators by manipulating Carter's duplicate.
