Big Mommas: Like Father, Like Son
FBI agent Malcolm Turner (Martin Lawrence) is elated to learn that his stepson, Trent Pierce (Brandon T. Jackson), has been accepted to attend Duke University in Durham, North Carolina. However, Trent is uninterested and instead wants Malcolm to sign a recording contract for him since he is underage. When Malcolm refuses, Trent's best friends encourage him to ambush Malcolm on the job in order to obtain the signature.
Malcolm, in an attempt to capture Russian gang member Chirkoff (Tony Curran), uses an informant named Canetti to deliver a flash drive to the gang, while Trent attempts to ambush Malcolm on the job. Canetti (Max Casella) reveals that the flash drive is empty and a duplicate is hidden with a friend at the Georgia Girls School for the Arts.
During the exchange, Canetti's cover is blown and he is killed, which Trent witnesses. Malcolm eventually rescues Trent and they escape, but since Trent's car was left at the scene Malcolm knows the gang members will be able to track them down so Malcolm and Trent are forced to hide undercover. Malcolm once again becomes Sherry's grandmother, Big Momma, and also disguises Trent as an obese girl named "Charmaine", Big Momma's great-niece. Big Momma takes a job as a house mother at the Georgia Girls School for the Arts, while Charmaine is enrolled as a student.
Surrounded by attractive young women, Trent nearly blows his cover, but manages to befriend a girl named Haley Robinson (Jessica Lucas). The headmistress announces that a historic music box has been stolen from the library, and Malcolm deduces that this music box contains the flash drive. While scoping out the library, Big Momma encounters security guard Kurtis Kool, who attempts to woo her while giving a tour. Seeing a picture of Kurtis with Canetti, Malcolm realizes that he is the friend, and tries to find out more about the music box.
Meanwhile, the gang members approach Trent's best friends, posing as record producers, and encourage them to notify them of Trent's whereabouts. Charmaine sets up a date between Haley and himself, though she doubts she will be interested in the seemingly egotistical "Prodi-G," Trent's hip-hop alias. Trent reverts to his true self and the date goes well, but an encounter with Trent's best friends causes the gang members to tail them.
Trent helps Haley perfect her musical performance for the upcoming "Showcase" event, turning it into a duet, and the two exchange a kiss at the end of the date, while Haley encourages Trent to pursue college. Before the gang members can capture Trent, he changes into his Charmaine disguise, throwing them off. Learning of an exchange between two students and Kurtis Kool, Big Momma attempts to flirt with Kurtis in order to apprehend him for stealing the music box, but the secret exchange ends up being the stolen gamecock from the Ignatius Boys School.
During this encounter, Malcolm reveals his true identity to Kurtis. After gaining the favor of several students by offering sage advice and comfort to them, Big Momma finally learns the music box was actually stolen by Haley as a hazing to become a full pledged member of the "Divas", a group of top artists in the school. As she is about to perform her duet, Malcolm forces Trent to retain his Charmaine disguise, and he attempts to perform the duet with Haley as Charmaine, only to break disguise and ruin the performance. As Haley storms off, the gang members arrive and a chase ensues.
Trent accidentally draws their attention as he attempts to pursue Haley and explain himself. Just as he recovers the flash drive, the gang members catch up and hold him at gunpoint. Big Momma interferes and provides an escape, but all three are caught again and Malcolm's disguise is revealed. Just as Chirkoff is about to kill them, Kurtis arrives with a taser and saves the day.
Trent and Haley reconcile, and Malcolm signs Trent's record contract, only to have him tear it up and reveal his new plan to attend college. As the film ends, Malcolm and Trent make an agreement to keep the whole ordeal a secret from Sherry. During the end credits, a music video is shown for Trent's song, "Lyrical Miracle". It features Malcolm as Big Momma, Kurtis Kool, the girls and the teachers from the school, as well as the gang members and the mailman.
