The film is based on manuscripts of the interrogations of Adolf Eichmann (Thomas Kretschmann) before he was tried and hanged in a prison in Israel. Eichmann recounts events from his past to an Israeli detective, Chief inspector Avner Less (Troy Garity), who is faced with the immense task of tricking the skilled manipulator into self-incrimination. While the world waits, Less's countrymen call for immediate execution, forcing him and Eichmann to confront each other in a battle of wills.
