One of them, guitar player Zdenek, begins to shun his friends' company. He has fallen in love with Vera, who does not belong to the group. The happy-go-lucky young man already has several acquaintances and has his own method to get a girl: to take his motorcycle, his guitar and a bottle of wine and take her to a rented houseboat. Vera, however, is different and gets angry at Zdenek. But she is fond of him and thus eventually spends a whole evening with him on the houseboat. At a preventative medical examination, the doctor tells Vera she is pregnant.
