Plot synopsis: In autumn 1941, Reich Protector Reinhard Heydrich’s brutal rule in occupied Bohemia and Moravia fuels Czech resistance. In spring 1942, the government-in-exile sends trained paratroopers led by Lt. Král on a mission to assassinate him. Masters Strnad and Vyskočil ambush Heydrich’s open Mercedes in Prague’s Libeň district, mortally wounding him despite a jammed submachine gun. Their success triggers harsh Nazi reprisals, mass executions, and an intense manhunt for the operatives.
