In this Disney film, Hank Cooper (Ed Asner) the owner of a losing professional football team, recruits Gus, a Yugoslavian soccer player, to his team. Even though Gus is a mule, he figures the animal can be taught to make field-goal kicks. Despite the outrage of his team, and sabotage efforts by Crankcase, Spinner and Gwymm (Tim Conway, Tom Bosley and Harold Gould), Gus the Mule kicks his team all the way to a championship.
