FBI agent Malcolm Turner goes back undercover as Big Momma, a slick-talking, slam-dunking Southern granny with attitude to spare! Now this granny must play nanny to three dysfunctional upper-class kids in order to spy on their computer hacker father.

After a high-speed car chase, Madea winds up behind bars because her quick temper gets the best of her. Meanwhile, Assistant District Attorney Josh Hardaway lands a case that's too personal to handle: that of a young prostitute and former drug addict named Candace, also a childhood friend. When Candace winds up in jail, Madea takes the young woman under her protective wing.

Madea winds up in the middle of mayhem when she spends a hilarious, haunted Halloween fending off killers, paranormal poltergeists, ghosts, ghouls, and zombies while keeping a watchful eye on a group of misbehaving teens.

Madea and the gang encounter monsters, goblins and boogeymen at a haunted campground.
