Crna mačka, beli mačor

Matko is a small time hustler, living by the Danube with his 17 years old son Zare. After a failed business deal he owes money to the much more successful gangster Dadan. Dadan has a sister, Ladybird, that he desperately wants to see get married so they strike a deal: Zare is to marry her. But none of the two care much for an arranged marriage: Zare is in love with Ida, Ladybird is waiting for the man of her dreams.
