The espionage thriller begins in 1997, as shocking news reaches retired Mossad secret agents Rachel (Helen Mirren) and Stefan (Tom Wilkinson) about their former colleague David (Ciarn Hinds). All three have been venerated for decades by their country because of the mission that they undertook back in 1965, when the trio (portrayed, respectively, by Jessica Chastain, Marton Csokas, and Sam Worthington) tracked down Nazi war criminal Vogel (Jesper Christensen) in East Berlin.

At great risk, and at considerable personal cost, the team's mission was accomplished - or was it? The suspense builds in and across two different time periods, with startling action and surprising revelations.
