Sledge Hammer is a tough-talking, mirror-sunglasses-wearing detective. He would shoot a jaywalker as readily as he would a fleeing escaped convict — and he seems happy to do it. His best friend is his pearl-handled, oversized .44 Magnum that he sleeps with and even talks to. Constantly suspended from the force, his case is usually solved and he is redeemed by his female partner.
Viola Johnson (Amanda Bynes) is in a real jam. Complications threaten her scheme to pose as her twin brother, Sebastian, and take his place at a new boarding school. She falls in love with her handsome roommate, Duke, who loves beautiful Olivia, who has fallen for Sebastian! As if that were not enough, Viola’s twin returns from London ahead of schedule but has no idea that his sister has already replaced him on campus.
Billy Regis (Chris Mulkey), a serial philanderer with an epically foul mouth, is less than delighted to hear that his downriver girlfriend Patti Rocks (Karen Landry) is pregnant with his child. To complicate matters, Billy has neglected to inform Patti about his wife and kids in Minneapolis. A frantic Billy persuades his straitlaced best friend, Eddie Hassit (John Jenkins), to come with him on a debauched overnight road trip to find Patti, admit his sins and persuade her to have an abortion.
