John Corey, former NYPD Homicide detective and special agent for the Anti-Terrorist Task Force, is back on the trail of Asad Khalil, the notorious Libyan terrorist known as 'The Lion'. Corey and his partner, agent Kate Mayfield, tracked Khalil across the US after his threats to wipe out the US in a horrific wave of terrorism. But after methodically eliminating his victims one by one, Khalil disappeared without a trace.

Now, years later, Khalil has returned to America to take care of unfinished business. 'The Lion' is a killing machine on a mission of revenge, and John Corey will not stop until he rids the earth of this tyrant once and for all.
