In a game show family Griswald wins a trip to Europe. They set out for Britain, France, Germany and Italy, ignorant to the damage they do to other people: In Britain Clark has slight problems to adapt to driving on the left side, runs several people over and accidentally lays down Stone Henge in reverse gear. In Germany they visit the wrong relatives and are chased by angry 'Schuhplattl' dancers. Finally in Rome they unknowingly help robbers in a hold-up and then Ellen gets kidnapped.
