After the war, Yaroslavl is uneasy. In the local shop, a saleswoman and a shopper are murdered. Some time ago, an elderly man was brutally killed: his decapitated body was dumped into a cesspit. To stop this horror, the police send Lieutenant Ilya Zhuravlev into a gang. He makes contact with the leader and learns that they plan to rob a train carrying expensive furs. It’s a great chance to catch the whole gang at once. Ilya warns his colleagues about the gang’s plans—unaware that he himself is already under their influence.
