When Rob Anderson (Marlon Wayans), a charming man-child, arrives in Charleston the night before he is about to marry the woman of every man's dreams, Megan Swope (Regina Hall), he hasn't written his vows, learned the steps for the first dance, or even remembered to bring the ring.
Instead of taking care of his responsibilities, Rob goes out for a night on the town with his best man (Jonathan Todd Jackson). Then something unexpected happens...
Rob wakes up naked in an elevator with no idea how he got there. When the elevator doors open Rob is shocked to find that it's late in the morning and he has only one hour to get to the church or miss his own wedding.
He tries desperately to get to the chapel, streaking through a city marathon, stealing clothes, avoiding capture by local police, a near death confrontation with a vicious motorcycle gang, and many other obstacles only to find himself waking up in the elevator again and again.
Some unknown force has conspired to make Rob live this hour repeatedly until he finally grows up and becomes the man that his amazing fiancée deserves to marry.
