A Happy Divorce (Un divorce heureux) (1975)

After having been rescued from suicide, a young man is the object of a bet by his doctor that the doctor can help him recover his joy in life. Ironically, the doctor's life is not a very happy one either, and his boast has a hollow sound. For one thing, although he seemingly has a "happy divorce," in which he, his ex-wife and her new husband are all great pals, it's not true. He wants his wife back. All sorts of complications arise out of these lies and distortions.
