A young photographer Dimda is shot in the open courtyard surrounded by high-rise buildings who lived there in a communal apartment. Murder investigation at the same time is also becoming a psychological research.

A young criminal investigation officer, Konrad Ulf, was charged with the murder of photographer Rudolph, who was shot in the yard of his house. The investigator finds out that on the eve of the murder the photographer quarreled with his neighbor Karlis - an invalid who hardly moves on crutches. In Karlis, Conrad recognizes his friend, who served with him in Afghanistan. Karlis admits in fulfillment of murder, but on a course of consequence it becomes clear, that he has stipulated himself. The investigator is sure: the key to the solution is a picture of a naked beauty, found in the photo archive of Rudolph.—Peter-Patrick76 ([email protected])
