In 1943, a reconnaissance detachment led by Captain Migunko is airborne by parachute into German-occupied Crimea. By an unexpected coincidence, the reconnaissance group seizes a car with Abwehr employees heading to the sabotage school. One of them, a German, dies, and the second - the traitor Dvigubsky - out of fear for his life, agrees to pass off the Soviet intelligence officer as a murdered German officer.
