Martin Lawrence reprises the role of FBI agent Malcolm Turner -- aka, undercover grandma Big Momma -- in this installment in the Big Momma's House franchise, Big Mommas: Like Father, Like Son. Malcolm's latest assignment teams him up with his teenage stepson, Trent (Brandon T. Jackson), who unwittingly makes himself a target when he witnesses a murder. In order to keep Trent out of harm's way and solve the case behind the killing that Trent saw, the two have no choice but to go undercover at an all-girls performing arts school, with Malcolm posing as the titular rotund old lady, Big Momma, and Trent dressing up as a heavy female student named Charmaine. ~ Jason Buchanan, Rovi
