Summer Holiday

Don and his mechanic friends Cyril, Steve, and Edwin convert a London Transport bus into a mobile home and drive it to southern Europe for their summer holiday. They pick up three young British singing group Do-Re-Mi members and an American runaway girl who disguises herself as a boy, Barbara, on the way to Athens in Greece. Along the journey, they encounter various quirky characters and get into humorous misadventures before performing an elaborate mime show to prove their entertainment credentials and escape from authorities.
