Quantum Break is set at and around the fictional North Eastern U.S. Riverport University where a time travel experiment has gone wrong. The event not only causes time to break down, but also grants the three main characters—Jack Joyce, Beth Wilder, and Paul Serene—the ability to manipulate time. For example, Serene, the main antagonist, can see into the future to decide which choices to make in the present; while Joyce, one of the two protagonists, can stop time. The two are pursued by Monarch Solutions, a corporation founded by Serene.
