For FBI agent Malcolm Turner (Martin Lawrence) this assignment should be a piece of cake. Set up camp across the street from Big Momma’s house and wait for Sherry, the ex-girlfriend of your bank robber target to visit her. There’s just one small problem though – Big Momma is out of town. A master of disguise, Turner decides to become Big Momma, inside and out. As his case progresses, he starts to fall for Sherry and must figure out how to get his man, and his woman.
