The son of a miller, following his call, flees to the sea, but after several years he returns to his family and to his childhood romance, Hanka.

The film’s plot is set during the war between Poland and the Soviet Russia (1919 – 1921). Wartime brutally encroaches on the life of a couple in love – Franek and Hanka. The Bolshevik troops cause damage to Polish villages and manor houses, and in one of the manor houses the invaders have a carousel. Luckily, the Polish cavalry comes to the relief just in time. Unable to wait passively, Hanka becomes a sister of mercy in one of the field hospitals near Vilnius, while Franek gains wide recognition after capturing a Russian spy.

Directed by Zbigniew Gniazdowski and Aleksander Hertz.
