Michel works there manically solving people's problems over the phone. He is about to tie the knot with his girl friend Isabelle, an airline hostess. She flies all over the world, he hates to leave the office. A series of madcap mishaps involving theft or injury (as you would expect in his line of work) ensues after Michel promises Isabelle nothing will delay their marriage and she promises in turn that she's done flying. Once this unlikely promise is made, it becomes premise and both are forced into escalating white lies to maintain the appearance of keeping their word. Their predicament mounts as Isabelle is forced to do a few more flights, while Michel is compelled to travel to New York, Tunisia, and finally Hong Kong, where they are finally reunited in the throes of a contrived and hilarious drug deal involving a 747, water taxi chases, and martial arts.

In this action comedy the French boxer Jo Cavalier is charmed on the train to Berlin for the Olympics in Hitler's Germany by the little boy Simon Rosenblum who asks his autograph; when it turns out his adorable young fan is a Jewish orphan in danger of persecution, he risks his one shot at Olympic glory to save Simon and his family, helped only by a German officer-gentleman who became his friend in World War I, by an adventurous escape to Switzerland, Nazi troops on their heals and braving impossible odds in roller coaster-style.
