Physicist Julie Vexler discovers a mathematical model that reveals a method for manipulating spacetime and traveling through time. In her new job at a research institute, she gets the opportunity to put her theoretical knowledge into practice and helps develop a time machine. But an experiment inadvertently alters the structure of time itself, causing past, present, and future to overlap. People remember things that never happened, historical events change spontaneously, and some people suddenly exist in multiple versions simultaneously or no longer exist at all. Julie and her friends discover that events in the past create new timelines and find a way to visit other versions of their world. An exciting journey through time and space.
