In Upload Season Three, we pick back up with Nora and freshly downloaded Nathan as they navigate their relationship, while racing to stop the mysterious conspiracy that threatens to destroy millions of lives. Can they shut down Freeyond, and finally have a real life together? Or is it just a matter of time until Nathan's head explodes? Meanwhile, in Lakeview, a backup copy of Nathan has been activated and Ingrid's not about to let this second chance at love slip away. Back in the real world, Aleesha rises through the ranks of Horizen by managing AI education, and falls into a new romantic relationship. And Luke, all alone in Lakeview, is forced to come up with the funds to pay for his stay in paradise, driving him to work in The Grey Zone.

Nathan is at a crossroads in his (after) life… his ex-girlfriend Ingrid has unexpectedly arrived to Lakeview hoping to strengthen their relationship, but his heart still secretly yearns for his customer service angel Nora. Meanwhile Nora is off the grid and involved with the anti-tech rebel group "The Ludds".
