In this innovative romantic comedy about the power of chance, alternate versions of the same wedding unfold as Jack (Sam Claflin) tries to make sure his little sister has the perfect wedding day. But he'll have to juggle an angry ex-girlfriend, an uninvited guest with a secret, a misplaced sleep sedative, and unexpectedly reuniting with the girl of his dreams who got away, Dina (Olivia Munn). If he succeeds, Jack might find a happy ending of his own.
