It used to be that no job was too large for superFed Malcolm Turner (Martin Lawrence).
These days, the thief-catcher is reduced to being a desk jockey, but he still hankers for the firing line. When he learns that cybercrook Tom Fuller (Mark Moses) has created a computer worm which could destroy Silicon Valley, Turner springs back into action.
Well, maybe not action, since none of the FBI's finest can get close to Fuller. But where others fail, inflatable agent Big Momma rises to the occasion, getting a job as the Fullers' nanny and befriending the villain's unhappy kids.
