Klima, a celebrated jazz trumpeter, receives a phone call announcing that a young nurse with whom he spent a brief night at a fertility spa is pregnant. She has decided he is the father.

And so begins a comedy which, during five madcap days, unfolds with ever-increasing speed. Klima´s beatiful, jealous wife, the nurse´s equally jealous boyfriend, a fanatical gynaecologist, a rich American at once Don Juan and saint, and an Elderly political prisoner who, just before his emigration, is holding farewell party at the spa are all drawn into this black comedy, as in A midsummer Night´s dream.
