A father, merchant navy captain, had three sons: Kirill – an artist, Yuriy – a sailor, and Gerka – a musician. It would seem that nothing could intervene in their friendship. However, the senior and middle brothers were in love with the same girl – Svetlana. The antagonism made them enemies. Yuriy could not forgive the unfaithfulness, and there was a big quarrel between the brothers. Suddenly, misfortune came thick on the family – fire on board of the ship killed their father. The distress brought the brothers together again.
