Slammin' Cleon Salmon (Michael Clarke Duncan), the former Heavyweight Champion of the world, is a mean, crazy, and sometimes infantile bull of a man, who happens to owe $20,000 to the head of the Japanese Yakuza and needs to come up with the money tonight. So he challenges the waiters in the restaurant that he owns, The Slammin' Salmon, a high end, boxing themed seafood eatery in Miami, to sell more food than they've ever sold in their lives, with the top waiter earning $10,000, the loser getting a broken rib sandwich. As the hours pass, the action becomes more chaotic as Cleon shows up to supervise the contest and changes the rules on a minute to minute basis.
