1993: Under deep cover, Nick Stone and a surveillance team's mission is to locate the boss of the world's most murderous drugs cartel and terminate him. 2012: Nick is in Moscow; semi-retired; semi-married to Anna; very much the devoted father of their newborn son. But when the boy falls dangerously ill and the doctor who saves him comes under threat, Nick finds himself back in the firing line. Nick Stone has two decades of operational skills-- and a fierce desire to protect a woman and a child who now mean more to him than life itself.
