When a woman he doesnt know, named Mascha Anna Lee, deliberately misdirects German soldiers close to finding him, he seeks her home as an alternative safe house. This turns out to be the home of her father, history professor Stephen Novotny Walter Brennan, whom the Nazis have banned from teaching. This plan works. But because the assassin now cant be found, the Nazi leaders in Prague decide to create an incentive for him to turn himself in or for others to do so. They arrangewith the help of fifthcolumnist Emil Czaka Gene Lockhart, a wealthy brewerfor 400 citizens, including Professor Novotny, to be executed, forty at a time, until the assassin is named. Through a complex series of events, however, the resistance manages to frame Czaka himself for the murder, but not before the Nazis have executed many of the hostages.A number of different working titles have been reported for Hangmen Also Die Never Surrender, No Surrender, Unconquered, We Killed Hitlers Hangman and Trust the People.
