Pop star Peter Frampton and the Bee Gees star in this musical, loosely based on the popular 1967 Beatles album Sergeant Pepper's Lonely Hearts Club Band. In the story, Billy Shears, who now heads the Lonely Hearts Club Band, is the grandson of the famous Sergeant Pepper. He is confronted by the need to save the magical musical instruments of the band from the bad guys, led by music tycoon B.D. Brockhurst (Donald Pleasance), who want to steal them. If they succeed, the magic which infuses "Heartland U.S.A." will disappear. Among the many Beatles' songs performed in the film by well-known popular artists are: "She's Leaving Home" (Bee Gees, Jay MacIntosh, John Wheeler), "Maxwell's Silver Hammer" (Steve Martin), "Got To Get You into My Life (Earth, Wind & Fire), "When I'm 64" (Sandy Farina), "Come Together" (Aerosmith), "Sgt. Pepper's Lonely Hearts Club Band" (sung by the Bee Gees, Paul Nicholas), "With a Little Help from My Friends" (Peter Frampton, the Bee Gees), "Fixing a Hole" (George Burns), and "Get Back" (Billy Preston).
