The film is based on the true events that took place in the Oryol prison in September 1941 and tells about 154 prisoners who were shot on September 10, 1941 without a court verdict (according to another version, they were drowned). The film uses staged filming: prisoners, men, women, teenagers sit on the floor in prison cells, eat, participate in an amateur concert. An NKVD worker dictates the text to a stenographer who types on a typewriter. Photos of people swirl in the air and fall onto the muddy and wet ground. The prison building is collapsing. Schoolgirl plays classics on the pavement. People with their hands raised behind their heads go down the stairs at the entrance of a residential building. The film includes counter-type footage: a rat runs across the floor of a prison cell, climbs on the glass of a window. Many photographs with portraits of different people are flying in the air. An empty prison cell with a sink in the corner. NDP. The grill of the camera is closed.
