Martin Lawrence is crafty FBI agent Malcolm Turner - who's willing to go through thick and thin in order to catch an escaped federal prisoner. Nia Long is Sherry, the con's sexy former flame. She might have the skinny on millions in stolen bank loot, and she's headed for Georgia to lay low for a while. That's enough to send Malcolm deep undercover as Big Momma, an oversized, overbearing Southern granny with an attitude as tough as her pork chops.
