Quinn Mallory, a graduate student in physics, sets out to invent time travel, but he accidentally discovers a method of opening gateways between parallel dimensions instead. Unfortunately, his control over this new means of travel is not perfect. When he tries to demonstrate his discovery, he ends up stranding himself, his coworker, his prickly professor and a musician in a strange world with no way home. The ragtag group travels through strange versions of the universe they know, including one where dinosaurs still roam, one where a vicious plague rages and another where the United States is ruled by a king. In their travels, they often encounter alternate versions of themselves and have to deal with their doubles in addition to the dangers found in each parallel universe.
