Sgt. Pepper's Lonely Hearts Club Band

Mr. Mustard (Frankie Howerd) and his henchman the Brute drive to Heartland in their computer- and robot-equipped van. Mustard gets orders via computer from a mysterious entity called F.V.B., who directs him to steal the magical instruments from City Hall, keep the drum, and bring the other instruments to them and others. Without the instruments, Heartland, now under Mustard's control, quickly degenerates into a hotbed of vice and urban decay. The band quickly succeeds with hit records and sold-out shows.
