The Beatles (John Lennon, Paul McCartney, George Harrison and Ringo Starr) head for London to appear on television, accompanied by their manager and Paul's grandfather (Wilfrid Brambell). Grandad gets into some trouble at a casino and then convinces Ringo to strike out on his own, but the boys find him just in time to play the big concert. Richard Lester's freewheeling directorial style set the tone for the Swinging Sixties.
