Kaviár jen pro přátele (1970)

A comedy about four "friendly" couples whose honesty, sincerity and also selfishness are put to an unexpected test. One of them, František, urgently needs to borrow twenty thousand crowns to buy a holiday cottage at a bargain price. The irony of the story is that Honza, who spontaneously lends him the money, becomes the object of suspicion in the company of calculating and suspicious friends.
