Gabriella, a striking, thirty year old Austrian Holocaust survivor is the driving force behind a secret Jewish organization (Nokmim) that hunts down Nazi criminals for the singular purpose of retribution. But her group, and much of the purpose of her life, is dying out. Flush with the success of capturing Adolf Eichmann in Argentina in 1960, Gabriella’s compatriots are turning away from the unsavory, back alley justice that is her specialty. Resistant to the changing tides, Gabriella heads to Central America on what could be her final assignment; tracking down Friedrich Guderian, an SS Major renowned for brutality in Chelmno and Treblinka concentration camps. Her search leads her to the Central Highlands of Nicaragua, where she crosses paths with Christian Logansfriar, a German missionary. Gabriella is forced to take up residence in a remote village while she tries to determine if Christian, a seemingly good and devout Catholic priest, is in fact the Nazi butcher, Friedrich Guderian.
