Big Momma's House III - 2011

The film begins with Malcolm Turner (Martin Lawrence) chasing down the mailman (Ken Jeong) to see if his step-son Trent (Brandon T. Jackson) got into Duke University, which he has. Malcolm goes home and tells Trent the good news, but Trent's not there. He goes to get Trent who is performing at a rap concert. When they go home, Trent tells his stepfather that he doesn't want to be a college student - he wants to be a rapper and needs Malcolm to sign a recording contract. When he witnesses a crime, Trent is forced to disguise as a girl, taking the name Charmaine Daisy Pierce in order to avoid getting killed. Malcolm disguises as his alter-ego, Big Momma, and hides Trent at an all-girls performing arts school to get a flash drive hidden in the school. Big Momma takes a job as house mother for the school. One of the girls, Jasmine, gives a warning to Big Momma: This is her school, and Big Momma better stay out of her way. Meanwhile Trent develops a crush on a student named Haley.

Later, Big Momma and Trent are having dinner with the other girls. Jasmine tells Trent that all the new girls have to do something to prove that they belong in the school and eat at least one time. It's rather: Sing, dance or act. Trent chooses singing and breaks into a rap with Haley's help on the piano. Big Momma gets on the table and starts dancing, breaking the table. The headmistress announces that a music box has been stolen and Malcolm figures that this must be where the flash drive was hidden.

Later that night, Malcolm as Big Momma runs into the security guard Kurtis, who hits on him. Malcolm gets Kurtis to take him on a tour and realizes that Kurtis was his FBI informant's friend and thus may know where the flash drive is. Malcolm learns from Kurtis that the girls may have stolen the flash drive and finds a necklace on the ground. Meanwhile, Trent attends a get-together with the girls where Haley gets a necklace as a member of the "Divas"; Jasmine isn't wearing one despite being a member. Malcolm and Trent surmise that Jasmine is likely the thief and strike a deal; if Trent helps Malcolm recover the flash drive, Malcolm will sign the contract....
