Frank Allen's meticulously structured life is about to become marvelously unraveled by one small, well-intentioned act of imposed spontaneity. Now, nothing will ever be the same as perfect synchronicity rapidly descends into a study in Chaos Theory. For Frank Allen (Ryan Reynolds--The In-Laws), celebrated author of the bestseller The Five Minute Efficiency Trainer, every choice is deliberate designed to contribute to a well-ordered, predictable life. Frank's wife, Susan (Emily Mortimer--Love's Labour's Lost), and seven-year-old daughter, Jesse (Matreya Fedor), find his obsession charming -- in small doses. One morning, Susan attempts to loosen her husband's scheduling stranglehold by setting his clock backward ten minutes, inadvertently unleashing a series of completely unplanned mishaps that turn his life upside down.
