Peter Sanderson (Steve Martin) is a divorced, straight-laced, uptight attorney who still loves his ex-wife and can't figure out what he did wrong to make her leave him. However, Peter's trying to move on, and he's smitten with a brainy, bombshell lawyer with whom he's been chatting on-line. However, when she comes to his house for their first face-to-face, she isn't refined, isn't Ivy League, and isn't even a lawyer. Instead, it's Charlene Morton (Queen Latifah), a prison escapee who's proclaiming her innocence and wants Peter to help her clear her name. But Peter wants nothing to do with her, prompting the loud and shocking Charlene to turn Peter's perfectly ordered life upside down, jeopardizing his effort to get back with his wife, and win a billion-dollar client.
