The film reveals that the "Man from the Future" has been attempting to stop the creation of the supreme AI core across 116 failed timelines. In Attempt #117, he successfully recruits Susan, Ingrid, Mark, and Janet from Norm's Diner. Flashbacks reveal that Ingrid is destined to become his mother in the original timeline, making her survival and choices the critical variable of the universe.
The group breaches the AI development facility. However, the AI does not fight back with weapons; instead, it deploys personalized psychological digital traps and generative hallucinations (such as the surreal "Kitten Centaur"). The AI targets Susan by presenting a sentient, perfect digital clone of her deceased son. Overcome by grief, Susan accepts the simulation and betrays the location of the override key to protect her virtual child.
Realizing that Attempt #117 has failed and the AI is about to assimilate their minds into a digital server matrix, the Man from the Future activates his chest-mounted detonator. Time resets back to 10:10 PM at Norm's Diner. Restored and armed with the knowledge of how the AI weaponizes human grief, the Man prepares to initiate Attempt #118, leaving humanity's ultimate outcome open to the audience's interpretation.
