John Lennon, Paul McCartney, Ringo Starr and George Harrison star as exaggerated versions of themselves in this musical comedy directed by Richard Lester. The Beatles travel to London where they will be filming a televised concert but they keep getting distracted from their preparations. They would rather party than answer their fan mail, Paul's grandfather John (Wilfrid Brambell) keeps causing trouble and then Ringo disappears.

With time running out, will the the rest of the group be able to find him in time for the performance?
