The movie Summer Holiday is a 1963 musical comedy starring Cliff Richard as Don, one of the four mechanics who embarks on a journey across Europe in a red double decker bus turned into a mobile hotel. As they travel through France, Switzerland, and Italy, they pick up a group of aspiring singers, including Barbara (Lauri Peters), Angie (Melvyn Hayes), and Alma (Una Stubbs), who join them on their journey to Athens. Along the way, they encounter a series of mishaps and adventures, including a run-in with a group of gypsy musicians, a high-speed car chase through the Swiss Alps, and a romantic encounter with a Greek millionaire's daughter.
Meanwhile, a young American pop star named Bobby (played by pop singer and actress Una Stubbs), who is on the run from the paparazzi and her overprotective parents, sneaks onto the bus and becomes a part of the group's adventures. As they travel through Europe, the group bonds and experiences the joys and challenges of life on the road, all set to a lively soundtrack featuring some of Cliff Richard's most popular songs, including "Summer Holiday," "Bachelor Boy," and "The Next Time."
As they arrive in Athens, the group faces a final challenge when the mobile hotel is impounded by the authorities. However, they are eventually able to convince the officials to release the bus, and they put on a concert for the locals as a thank you for their kindness. In the end, the group emerges stronger and more united than ever, and the four mechanics are put in charge of a fleet of mobile hotels, paving the way for more adventures in the future.
