Dr Ganevski leaves his wife Maria and his grown-up children Rositza and Chavdar for Dr Troyanovska, who has been widowed by the war. Her son, Angel, a school dropout, is in love with Rositza. Rositza renounces her father. Up to a point, Chavdar can understand Ganevski's decision. Hoping to live in affluence, the boy moves in with his father's new family.
