In the mid-21st century, Jacques, his son Derrida, and his friend Nathan report a major bug in their new androids' operating system, but meet resistance from Jacques' superior, Andrei; a horrifying turn of events sends Derrida on the run.

Derrida learns he slept for 10 years while Andrei's militarised androids went to war with the world. He meets new allies and attempts to track down Nathan's daughter Mage, who he promised to protect.

Derrida stops by Nathan's old house and runs into Mage's best friend Yuri, who is now a young woman. Yuri gives Derrida devastating news, but his grief is cut short when they're attacked by a woman in black.

Derrida and Vidaux head underground to break into Rebuild headquarters, where they hope to find information that can lead them to Mage.

While searching a museum for Mage, Derrida recalls a time he spent there with his father, which has a surprising effect on his present self.

Vidaux goes to the city to fix a badly damaged Graham, who has suffered after repeated battles; Derrida tests his ability to time travel.
