Savanyú and his friends work at a plant. After the monotonous shifts they engage in the pleasures of the afternoon and the night: Sex, parties and concerts. Savanyú dates Juli, who works in workers hostels with the other girls. They are already engaged, but have almost no time to spend together. At a concert held in the Park of Youth, Juli gets to know Géza. They flirt and eventually travel through the country with a pop-group. Savanyú goes after them and catches up with Géza and the pop-group. A minor fight cools the atmosphere. Juli must decide, and her choice is Savanyú. Nothing can stop the wedding now.
