One year ago, former Israeli intelligence agent Thomas Hirsch (Martin Freeman) heard about ex-Mossad spy Rachel (Diane Kruger) for the last time. After being sent by Thomas to Iran for a dangerous assignment, she fell in love with the target person, businessman Farhad (Cas Anvar), and has since gone underground. But now the Mossad contact man hears her say at the other end of the line that her father has died. Yet again. At the intelligence service, therefore, all alarm bells ring, so Thomas is summarily summoned to a crisis meeting. He now has to remember everything he knows about Rachel. Finally, she carries explosive knowledge and all sorts of intelligence secrets that could become extremely dangerous in the wrong hands. So while he’s trying to help the ex-spy, let him find out if she’s a threat.
