The Bundys win a free trip to England, courtesy of the village of Lower Uncton, which can rid itself of a centuries long curse by ridding the world of male Bundys, and there are only two left, Al and Bud. Back in 1653, an ancestor of Al's, Seamus McBundy, a chauvinist blacksmith, insulted a fat, ugly witch who then imposed a curse on all future Bundys and the town which sits in a time warp of permanent darkness. The Lower Uncton residents, led by historical Winston, and his cohort Igor try to lure Al and Bud in their town limits to kill them to end the curse while the rival Upper Uncton residents, led by assassin-for-hire Trevor, must endure they die outside the town so the curse does not get lifted and ruin their reputation as a tourist town.
