1942, the German command is eager to take revenge after the catastrophic defeat at Stalingrad. To prepare the ground for the upcoming counteroffensive, several groups of highly trained German saboteurs are sent into the Soviet rear. Their task is to carry out a series of sabotage operations, the ultimate goal of which is unknown, but the success of the upcoming German offensive directly depends on it. A reconnaissance group under the command of Andrey Losev enters into a deadly battle with the German saboteurs. The enemy is strong and cunning and seems to have some kind of mystical sense that helps him to always be one step ahead. But our scouts are indomitably on the trail of this dangerous "beast".
