My Sinful Husband

The student Marta Hančová wants to work in the laboratory of growth factors in the Institute of Molecular Biology and Genetics after her graduation. She successfully passes the demanding final exams and indeed gets the desired job. But she becomes pregnant by her colleague Zdeněk Hradecký even before her degree ceremony. Freshly married, she selflessly works on a research assignment with Vašek Hořák who loves her platonically. Her husband Zdeněk, too, begins at the institute. He is much less competent than his wife but, instead, much more ambitious. His snobbish mother blames Marta for her insufficient care for the household. She does not let the young couple live in her villa but keeps inviting her son over. The birth of daughter Anička interrupts Marta's promising career for a while. Her friend Irena has not finished her studies and decides to never have children due to her career as a singer. When there is the danger that the institute will employ someone else instead of Marta after a year and a half, Marta hands the daughter to the care of her mother-in-law and returns to work. Zdeněk wants to get the position of head of the cellular physiology department after a colleague retires and is ready to do anything to get it. Marta is tired; she even falls asleep on her way back from work on the subway and only wakes up in the depot. Grandmother Hradecká refuses to take care of her granddaughter any longer and the young parents must find a babysitter even though it is very expensive. Quarrels pile up between the husband and wife. Zdeněk reproaches Marta for neglecting their daughter and supporting Hořánek who is the second candidate for the leading position. The mother-in-law wants Marta to sacrifice her career to her husband's. The nanny falls asleep while babysitting Anička. Marta looks for Zdeněk at work and at his parent's home, but in vain because her husband is dating a lover, the director's wife. Zdeněk offers to the director that he will entertain visitors from abroad in his home. He automatically expects Marta to attend to them, and she thus introduces herself to the guests as a hired auxiliary. When the director behaves too intimately towards her, she slaps him across his face, lands Zdeněk another one and leaves the flat. Irena, however, cannot let her stay at her place; her professional career has finally commenced. The selfless colleague Vašek takes Marta and Anička in and offers to let them share his flatlet. Marta likes him but is unable to return his love. She decides to give up research and start teaching. The psychologist at a marriage guidance bureau is unable to help the Hradecký couple who are at sixes and sevens all the time. The director offers Hořánek the position of department head. Vašek refuses – he surely wants to care for Marta. But the woman convinces him that such scruples are senseless. Zdeněk breaks up with his lover and sobers up from his excessive ambitions. He takes Marta back to their flat and wants to wait at his parents until his wife decides. But Marta herself does not know.
