A Chicago librarian suffers from a rare genetic disorder that sends him hurtling through time whenever he is under extreme duress; despite the fact that he vanishes at inordinately frequent and lengthy intervals, he attempts to build a stable future with the beautiful young heiress he loves. Eric Bana and Rachel McAdams star in this dramatic fantasy, which is directed by Robert Schwentke and based on the best-selling book by author Audrey Niffenegger.
