Hired by a powerful member of the Russian mafia to avenge an FBI sting that left his brother dead, a psychopathic hitman known only as The Jackal proves an elusive target for the people charged with the task of bringing him down: a deputy FBI director, a Russian MVK Major, and a jailed IRA terrorist who can recognize him.

But when Diplomatic Security Agent John Royce is assigned to help Gerard recapture Sheridan, it becomes clear that Sheridan is more than just another murderer.
