Plot summary

Renton (Robbie Amell) wakes up beside his former lover, Hannah. (Rachael Taylor) Three men break into his bedroom and take him hostage. Renton breaks his neck while escaping and wakes with a start, only for the men to break in once again. He and Hannah are taken to another room and bound to chairs. The leader of the group introduces himself as Father (Gray Powell), identifying the others as Sonny (Shaun Benson) and Brother (Jacob Neayem); Cuz (Adam Butcher) died of electrocution after touching a large device, the ARQ (Arqing Recursive Quine), in the room. Father says he represents a rebel group known as the Bloc and demands Renton surrender money, or "scrips", from their rival organization, the Torus Corporation. He gives them several minutes to comply and leaves the room with the others to get food.Renton explains to Hannah the ARQ is a working perpetual motion machine he designed at Torus. After Torus shut down the project as an impossibility, he stole it. Renton believes the Bloc members to be after the ARQ rather than the scrips, though Hannah urges him to comply with their demands. After freeing himself and Hannah, he is killed while trying to escape. Renton wakes up gasping, only to relive the same scenario. This time, after freeing himself, he asks Hannah to help poison the intruders with cyanide gas. This fails when Hannah reveals herself as allied with them. Renton surrenders the scrips, only to be killed again after Sonny shoots him.After reviving, Renton questions Hannah about her past. She says she grew to resent Renton after he abandoned her to Torus, who tortured her. Renton says he never gave up looking for her after he escaped. Though he does not trust Hannah, Renton frees her. They work out a deal where they will split the scrips after using the cyanide gas to force Father and his group to stand down. Renton reneges on the deal, demanding that Hannah abandon the Bloc and come with him. She refuses and accidentally shoots Renton during a scuffle. Renton and Hannah wake in bed; this time, both recall the events. When Renton says the ARQ is causing a time loop, Hannah insists he give the technology to the Bloc. Renton figures that the ARQ is resetting itself to the time when Cuz got electrocuted when he touched the ARQ. He is not willing to shut down the ARQ until he is in control of the situation. Eventually, Sonny reveals himself as a Torus mercenary and kills everyone.When they wake, Renton and Hannah agree they must keep the ARQ from Torus, though Renton expresses distrust in the Bloc. They convince Father to help them, but Sonny shoots Father and knocks Brother unconscious. After killing Sonny, Renton applies first aid to Father. He dies after Brother shoots him, not realizing Sonny is responsible. The next iteration, Sonny becomes aware of the time loop and immediately kills Father and Brother. Renton theorizes the ARQ is looping the same three-hour period due to running out of energy. Instead of producing unlimited energy, its fuel cells are refilled after every loop. When Sonny overpowers them, Renton sacrifices himself to prevent Sonny from acquiring the ARQ.In the next iteration, Sonny saves Cuz's life, then kills Father and Brother. Renton and Hannah poison Sonny and Cuz with the cyanide. Before dying, Sonny uses the pool of blood from every other corpse (including Cuz, whom he kills) to set up a trap. After arguing not to destroy the machine, Hannah is electrocuted when she accidentally steps on Sonny's trap. Renton briefly considers destroying the ARQ but allows the next iteration to begin. He admits he was wrong and offers the ARQ to the Bloc. Father, who is now aware of the time loop, and Brother agree to work with Hannah and Renton; however, Sonny and Cuz take all hostage. After Sonny forces Renton to disable the machine, Father and Brother die in the confusion of a blackout. Renton and Hannah briefly escape but return once they realize the time loop is localized to the house.After they kill Cuz, revealed to be a torturer for Torus, Sonny restarts the ARQ, only to be killed. An interrupted video message and the ARQ's logs reveal a second, outer time loop: every nine-time loops form their own loop in which their memories are reset. Unknowingly, they have repeated the same nine loops' thousands of times. Realizing they are on their ninth loop, Renton and Hannah leave a desperate message to themselves, hoping future iterations can get the ARQ to the Bloc before Torus' reinforcements arrive. After a robot breaks through and kills them, Hannah wakes with a gasp.
