Drawing from their experience (both took part in the underground resistance), Binka Zhelyazkova and Hristo Ganev reveal with great verve and passion the activities of a young underground combat group operating in Sofia. The bombings, the spreading of propaganda leaflets, giving refuge to underground fighters, nocturnal walks in the park and the city streets, a visit to the ballet performance, ruthless tortures in jail - all these scenes are marked by highly expressive cinematic style. The play of flashlights of two central characters, Veska and Dimo, which dance on the sidewalk, now losing, now finding each other is one of the most memorable cinematic images.
