Two FBI agent brothers, Marcus and Kevin Copeland, accidentally foil a drug bust. As punishment, they are forced to escort a pair of socialites to the Hamptons, where they’re going to be used as bait for a kidnapper. But when the girls realize the FBI’s plan, they refuse to go. Left without options, Marcus and Kevin decide to pose as the sisters, transforming themselves from African-American men into a pair of blonde, white women.

When Ashtray (Shawn Wayans) moves to South Central L.A. to live with his father (who appears to be the same age he is) and grandmother (who likes to talk tough and smoke reefer), he falls in with his gang-banging cousin Loc Dog (Marlon Wayans), who along with the requisite pistols and Uzi carries a thermo-nuclear warhead for self-defense. Will Ashtray be able to keep living the straight life?

After leaving the prison, the dwarf criminal Calvin Sims joins to his moron brother Percy to steal an expensive huge diamond in a jewelry for the mobster Walken. They are chased by the police, and Calvin hides the stone in the purse of the executive Vanessa Edwards, whose husband Darryl Edwards wants to have a baby. Percy convinces Calvin to dress like a baby and be left in front of the Edwards’s house to get inside the house and retrieve the diamond. Darryl and Vanessa keep Calvin for the weekend and decide to adopt him, while Walken threatens Darryl to get the stone back.
