Walter Bergman is a boring old travel agent. While away on a business trip, he finds an investor in a swinger and starts hanging out with ‘The Groovy Bunch’, adherents to the swinging lifestyle. But will he embrace the lifestyle, or just find a monogamous younger upgrade on his wife?
This is a German-American co-production of sorts, with some American inserts (apparently shot at same location) put into the original German film. German title: Heißer Sand auf Sylt
