When one Israeli citizen disappears from Charles de Gaulle airport with a woman in a red dress, you could put it down to youthful indiscretion.
When a second from the same flight is disappeared from his hotel room by a girl with a gun, you might just have a diplomatic crisis on your hands.
Enter Colonel Abadi, recently appointed head of the special branch of Unit 8200, Israel's most secretive intelligence service.
His only allies are his deputy back in Israel, the dazzling and hot-headed Lieutenant Orianna Talmor, and a hungover French detective, hung out to dry by his superiors.
Together they face a squad of ruthless Chinese commandos who have no qualms about leaving Paris littered with bodies.
And then there are their enemies in the Paris establishment and the labyrinthine, back-stabbing Israeli intelligence community.
All in all, it could be a long night.
