PLOT
Lieutenant Gabor's plane drops intelligence officer Benkov behind enemy lines. Benkov is assisted by his sweetheart Marja, also an intelligence officer and partisan, to carry out his mission. The Gábors' next trip also takes them behind enemy lines, to photograph a hidden railway line. They prepare the shots, but are discovered, get into a firefight and have to make an emergency landing. Luckily they reach Marja's hut and Benkov hides them. The partisans discover their hiding place and Marja and Benkov are shot dead. Lieutenant Gabor covers the retreat of his comrades by sacrificing his life, so that the important recordings and Benkov's report reach their destination.
