High-school basketball player Luka is having an affair with the much older, married Dina, who comes along to his every game and gazes yearning at Luka from the stands. To her, their assignations seem all too short; in order that they can spend more time together, she arranges with stolid businessman husband Gantar, that they should hire Luka as math tutor to their son Andrej, who's struggling with the subject. But it becomes pretty obvious to Gantar what's going on between his wife and Luka, as it does to Andrej, who has developed a major crush on his tutor. When Andrej passes his exams, Gantar throws a party at the house for Luka and all his friends and it turns to a sex party. Luka sees Dina in the midst of violent sex with Gantar. Luca and Gaspar fight. Disgusted with Dina, and not realizing that what he stumbled upon was an act of rape, Luka sets off on a long motorbike tour with Petra. When he finally returns home, having determined that he's fallen in love with Petra, he discovers Dina in mourning. Although she kept his involvement from the police, Gantar never arose after Luka knocked him down. She's unwilling to tell the cops that Luka killed her husband . . . assuming, of course, that he abandons his young hussy and returns to Dina's arms.
