CIA case officer Sam Joseph is dispatched to Paris to recruit Syrian Palace official Mariam Haddad. The two fall into a forbidden relationship, which supercharges Haddad’s recruitment and creates unspeakable danger when they enter Damascus to find the man responsible for the disappearance of an American spy. But the cat and mouse chase for the killer soon leads to a trail of high-profile assassinations and the discovery of a dark secret at the heart of the Syrian regime, bringing the pair under the all-seeing eyes of Assad’s spy catcher, Ali Hassan, and his brother Rustum, the head of the feared Republican Guard.
