Jirka Horáček, a teenager living with his father on a Pilsen housing estate, spends his free time at discos with friends. One night he meets the confident blonde Eva, who is already involved with an older suitor, Cáfa, and also encounters the kind Jitka. Despite Jitka’s interest, Jirka becomes infatuated with Eva and tries to win her favor, all while his reckless pursuits strain his relationship with his impatient father.
