With a bump to the head, Jamal Walker (Martin Lawrence) finds himself transported from his job at a medieval theme park to the real Middle Ages, where he teams with ex-knight Sir Knolt (Tom Wilkinson) and chambermaid Victoria (Marsha Thomason) to take out the evil King Leo (Kevin Conway). The hilarity begins as Jamal clashes with Leo and his henchman, who've stolen the throne from Queen Victoria (Helen Carey) in director Gil Junger's comedy.
