Cornfed invites Beverly to join him on a trip to his Aunt's catfish ranch. Duckman, jealous of Cornfed's interest in Bev, tags along for the ride. After getting the ranch hands fired, Duckman and the gang must help the foreman, Big Jack McBastard, on the big catfish drive to Texas. On part of their drive involves crossing "Hell's Toilet", where "the days are so hot they can boil your brain and the nights are colder than David Caruso's film career". After Duckman accidentally kills Big Jack, they are on their own.
