Hazzard's annual Hazzard Derby is on. While Cooter is injured trying to help the Dukes, Luke must race in Cooter's car while Bo is in the General Lee. However, all the entrants who signed the contracts didn't see the fine print that every loser will have to give up their cars to Boss Hogg. Rosco's car can't lose with a tank of nitrous oxide in the engine. With a sure win, Boss bets with a big time Chickasaw bookie, Ma Harper.
