"In an effort to untangle himself from the previous episode's cliffhanger finale, Wallace seeks admission into the prestigious Prickly Thicket country club, an association disdained by the Flitt family due to a centuries-old dispute. But once Wallace is admitted into the club, he learns of a much larger mystery that must be solved to protect the West Wallaby Street lifestyle he and Gromit hold dear. Built by Wallace and Gromit's ancestors, the club itself is a grand machine in the style of Wallace's own inventions, and its mechanical inner-workings hide a secret that must be recovered to return life back to normal."
