Můj brácha má prima bráchu (kolekce)

Honza Pavelka (Jan Hrusínský) wins the junior motorbike speed races. His thirteen-year-old brother Martin (Roman Cada), his assistant and biggest fan, answers the questions of his schoolfriend Pavlína in a superior tone. Student Zuzana (Libuse Safránková), who gave her scarf to Honza to wear around his neck for the races as a talisman is Honza's girlfriend. He met her when he came to her parent's home to repair the TV set. Honza declines an invitation to celebration with his friends. He goes off with Zuzana instead, but she refuses his intimate advances. The offended young man, who is about to serve his two years in the army, tries to blackmail her emotionally and the couple breaks up. Martin tries various schemes to bring them together again.

Honza and Zuzana are very young husband and wife. They have a little daughter of whom willingly occasionally take care the grandparents and Honza's fifteen-year-old brother Martin. Zuzana continues studying and Honza devotes all weekends as an amateur competitor to the motor-cycles at the speedway. Zuzana is not interested in motor-cycles. Martin holds responsible for his brother's marriage and at the advice of his friend Magda, who is of the same age, invites her sister-in-law to the club of Hucul horses so that she does not feel bored. But by misfortunes and unexplained quarrels both young husband and wife start being jealous of one another.
