 The year is 1943. Colonel Vishnevskiy (Andrei Panin) receives an order from the government to train a group of saboteur soldiers who should stop the actions of a German army group called "Edelweiss". The mission is a top-secret one. Vishnevskiy trains young (14-to-15-year-old) boys from juveniles. They all know that after the mission is finished they all will be eliminated since they all know too much to be left alive.
