The first of six episode compilations of the TV show released theatrically, featuring episodes 1 and 3. In 1941, Polish soldier Stanisław Kolicki escapes German captivity only to be mistaken for the dashing Abwehr lieutenant Hans Kloss and recruited by the Soviets as their secret agent J-23. Under deep cover behind enemy lines, he feeds crucial intelligence to the Red Army while outwitting suspicions and dueling wits with the formidable SS officer Hermann Brunner.
