Big Momma's House 2 (2006)

Big Momma is back in full-figured force in this sequel to the hilarious hit film "Big Momma's House". FBI agent Malcolm Turner heads west to a very active lifestyle in sunny seaside California where he must go deep undercover to avert a national security disaster. Really deep. Nanny deep. He resurrects Hattie Mae Pierce, affectionately known as Big Momma, to infiltrate the Fuller family by taking charge of three young children, a depressed dog and a troubled household while simultaneously fighting bad guys, and keeping his kid-phobic true identity a secret.
