“火焰”和"柚子"是丹麦最重要的通缉犯,德军盖世太保头目霍夫曼将他们定为头号公敌。在执行某次刺杀德军军官的行动时,吉尔伯特掺和进了“火焰”和“柚子”的任务中。扑朔迷离、敌我不明的形势下,“火焰“和“柚子“决定自己行动,从而卷入了巨大的危险之中...During Nazi occupation, red-headed Bent Faurschou-Hviid ("Flame") and Jørgen Haagen Schmith ("Citron"), assassins in the Danish resistance, take orders from Winther, who's in direct contact with Allied leaders. One shoots, the other drives. Until 1944, they kill only Danes; then Winther gives orders to kill Germans. When a target tells Bent that Winther's using them to settle private scores, doubt sets in, complicated by Bent's relationship with the mysterious Kitty Selmer, who may be a double agent. Also, someone in their circle is a traitor. Can Bent and Jørgen kill an über-target, evade capture, and survive the war? And is this heroism, naiveté, or mere hatred?
