 An apocryphal version of the assassination of the Nazi leader and Czech "protector" Reinhard Heydrich by a resistance fighter in World War II. The story follows the assassin as he evades the widening Nazi dragnet, protected by his fellow Czechs even to the point of self-sacrifice. As the Czech people are put to the sword in increasing numbers in retaliation for the assassination and their refusal to give up the killer, a plan evolves to provide the Nazis with an "assassin" who is actually a Czech traitor.
