Peter Sanderson (Martin), a divorced, straitlaced, uptight workaholic lawyer, meets a brainy, bombshell barrister in an online chat room and they make a date. Expecting his soul mate, he opens the door and finds himself face-toface with Charlene (Latifah) – a wild and crazy soul sister whos just escaped from prison and wants Peter to clear her name. But Peter wants absolutely nothing to do with her, and that prompts Charlene to turn Peters perfectly ordered life totally upside down. Hysterical complications abound and Peter soon finds out he may need Charlene just as much as she needs him.
