Lieutenant Vasátko is spending Christmas vacation in a mountain cabin where a diverse group of people have gathered. The painter Horác and two married couples, the director Skorkovský and his wife and his new discovery, the not very clever Jájinka and her husband. There is a murder and an unusual denouement.
