Herbert Cukurs is an officer in the Latvian Air Force and his country's most celebrated pilot. But after the Nazi invasion, he earns the nickname The Hangman of Riga after joining forces with the fascists, and is responsible for the extermination of 30,000 Latvian Jews. Twenty years later, Cukurs is living quietly in Sao Paolo, Brazil. That is, until the Nazi-hunting unit of the Israeli secret service tracks him down.
