No Way Back.

In October 1943, Red Army Major Toporkov, after escaping a concentration camp, informs a partisan detachment about a planned uprising in the camp and the need for weapons. The commander sends two convoys: one with real weapons and another with fake ones to mislead the Germans, aware of a traitor in their ranks. The convoys navigate through Polesie, thickets, and swamps, pursued by German forces, with no return.
