A former agent of Mossad, the Israeli secret service, Rachel Singer (Helen Mirren) is a national heroine in her homeland. Back in 1965, she embarked on a top secret mission to East Berlin, along with fellow agents David (Ciaran Hinds) and Stefan (Tom Wilkinson).
Their task had been to track down notorious Nazi war criminal Dieter Vogel (Jesper Christensen) - the sadistic Surgeon of Birkenau.
But three decades later in 1997, doubt is cast on the success of this mission. Plagued by memories of her younger self (played by Jessica Chastain), Rachel is forced to revisit her past and the dangerous role she played as human bait.
Building suspense in two timeframes, this gripping espionage thriller from John Madden ('Shakespeare in Love') was co-scripted by Matthew Vaughn and Jane Goldman ('Kick-Ass'), who spring plenty of extraordinary revelations.
Screenplay: Peter Straughan, Matthew Vaughn, Jane Goldman
