During the winter of 1941/42, the Second World War comes to a temporary standstill on the Eastern Front yet both Nazi and Soviets are putting everything they got in order to turn the tide in their favour. Spiritualists of Ahnenerbe summon the long-dead baron von Wolff from the world of the dead. To counter this plan, special occult branch of the Soviet Intelligence, called 6th Division, deploys it's best agent - 14-year-old esper girl Nadya, the only survivor from the special operations unit of 6th Division - the "First Squad".
