Sei has infiltrated impenetrable buildings, eliminated formidable opponents, and executed high-profile targets but the only mission that matters—finding her daughter—continues to elude her.

A tip leads her to a Tunisian immigrant living in Paris who may have information on the man she believes has kidnapped her daughter: the Black Wolf. While questioning the source, Sei learns about another individual involved in the abduction of her daughter—a man so vile, so foul in every way, that the mere thought of him turns Sei’s stomach. Has her daughter fallen victim to him?

To make matters worse, Sei comes to the realization she must do the unthinkable when she finds this sicko. She must befriend him.
