This heroic comedy is based on the short novel “Sergeant Tsybulia’s Autograph” by P. Avtonomov. Sergeant Tsybulia, a young intelligence agent, after completing another mission, on a “countryside trip” at the Germans’ back again. He is now charged with the mission of delivering medicines, provision and explosives to the partisans. His nocturnal parachute jump from plane proves to be a failure. Tsybulia takes enemy’s campfires (which the polizei use to cook pigs expropriated from the population) for partisans’ identification lights, and lands right in the den of the enemy. He outwits his pursuers, imprisons a German major and breaks through to the partisans’ positions onboard the enemy’s armored train.
