When journalist Ronnie Bart visits a Rome clinic, where one of his colleagues lies drugged, he becomes involved in a series of adventures in which fear and death are never far away.
In a Copenhagen nightclub, Bart meets a young millionaire, Paul Arved, and goes with him and his ''flying circus'' of girls and hangers-on in a private jet to the South of France. They then proceed to Sicily, where the story reaches a dramatic, violent finale.
