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.
