The Seven Ravens

November 1944. The Ostrava Gestapo order an informant Čermák to find and catch an escaped Russian prisoner who has been working in underground a factory on the production of a secret weapon. In the Beskids Mountains seven fugitives - seven ravens - meet in a half-burnt cottage. They include men who want to fight against the Germans, but also a Jew in hiding to avoid the transports, a black-marketeer and the young Russian Viktor. The energetic Lojza takes command, and with the help of the gamekeeper Jožin he re-establishes communication with a partisan brigade led by Jenda. At a joint action - the blowing up of a bridge, however, they are surprised by the Germans. Everyone believes that someone must have betrayed them. Their suspicions are confirmed by the gamekeeper, which finds a message for the Gestapo under a tree-stump. Victor senses that the others do not trust him, and playing cards he takes action, putting together samples of the handwriting of everyone in the group and setting off after the gamekeeper to compare them with the writing on the message. Before the men have time to talk, however, Viktor has to escape from the approaching villagers. After returning from a meeting with Vašek, one of the "ravens", the gamekeeper's daughter Zuzka finds her father murdered. Panic breaks out in the group. The men all suspect each other and no one trusts anyone. Tension rises and ends in shooting. Only Pavel, Vašek and Viktor remain alive. The message that he took from the gamekeeper falls out of Vašek's pocket. The men flee further into the mountains. One of them is a traitor.
