Carl Allen (Jim Carrey) is a guy whose life is going nowhere—the operative word being "no"—until he signs up for a self-help program based on one simple covenant: say yes to everything...and anything.

Unleashing the power of "YES" begins to transform Carl's life in amazing and unexpected ways, getting him promoted at work and opening the door to a new romance. But his willingness to embrace every opportunity might just become too much of a good thing.
