Upload’s return promises dark AI, chinchilla life coaches and a love story for the (digital) ages in the new trailer for the Prime Video series’ final season. 

The sci-fi comedy’s four-part finale event was previously teased during San Diego Comic-Con with a look at Aleesha’s (Zainab Johnson) new life as a spy tasked with infiltrating Horizon, the company in charge of running Lakeview. Now, as part of a new two-minute teaser (below), the Prime Video series picks up where season three left off, revealing the fate of Robbie Amell’s two Nathans inside that digital afterlife. 

As a ragged-looking Nora (Andy Allo) discovers her version of Nathan has seemingly succumbed to deletion and somehow returned as a digital ghost, she sets out to not only convince the others that he’s alive, but to save and reunite with him. 

Meanwhile, Ingrid (Allegra Edwards) and her Nathan navigate the unique challenges of a virtual relationship, alongside Nathan and Luke (Kevin Bigley) affirming their friendship as the rest of Lakeview faces new threats. That includes ownership focused on increasing monetization, a tall, dark and threatening AI Guy (Owen Daniels), and the potential full-blown destruction of Lakeview with everyone inside. 

The four-part finale event promises one final battle as a new sentient evil AI threatens to wipe out the world, testing the series’ core ensemble — Nathan, Nora, Ingrid, Aleesha, Luke and AI Guy — like never before. 

Created by Greg Daniels, who also serves as executive producer along with Howard Klein and Maxwell Vivian, Upload’s fourth and final season will premiere on Aug. 25.
