Storyline:

A fabulous 60s Musical - 4 London Bus mechanics strike up a deal with London Transport. They do up a double decker London Bus, drive it around Europe as a hotel and if they make it they will own and be in charge of a whole fleet. While on the road in France they pick up 3 ladies whose car breaks down and offer to take them to their next singing job in Athens. They also pick up a stowaway. A young, American boy. Meanwhile, a young American female singer has gone missing. Her mother (who is a VERY ambitious woman) and her aid take the story to the press and it makes the front page. They do all they can to make the story run for as long as possible, including misdirecting the bus up an extremely steep Yugoslavian hill. We find out the young American boy is actually the young American girl who is missing. Mayhem ensues as the lead character, Don (Cliff Richard) falls for Barbara. Eventually, when the 8 bus riders reach Athens, they're arrested for kidnapping. In front of her mother and a Ballroom filled with world-press, Barbara and Don declare their love for each other and the mother accepts (after realising how 'big' Don will become). When the film ends, all eight people are at a Grecian beach and very much enjoying their well deserved holiday!
