Chicago homicide detectives Jack O’Keefe and Scotty Johnson are street smart cops who will stop at nothing to bring a murderer to justice. But each partner’s role of detective is challenged after he is assigned to guard a prisoner by the name of Mark Pierre who Scotland Yard desperately wants brought back to England. Nelson Montgomery, the head of Scotland Yard’s Anti-Terrorist Unit, requests that Pierre be held in Chicago Police custody until arrangements can be made for his safe return. Montgomery reveals that there is a contract out on Mark Pierre’s life and an international assassin, known as the Fox, has the contract. The Fox’s actual name is Kevin Durkin, a former IRA terrorist, but no one in Scotland Yard or Interpol can identify him. It rests with O’Keefe and Johnson and their supervisor, Lieutenant Louie Carter, to keep Pierre from being killed.
Durkin, the Fox, arrives in Chicago to fulfill the contract on Mark Pierre. And it is on a dimly lit stairwell landing at the St. James Hotel that he shoots Detective O’Keefe leaving him for dead. The Fox kills Mark Pierre along with Johnson and Carter before fleeing to the west of Ireland. O’Keefe survives the shooting and Nelson Montgomery arranges for the American detective to be sent to Ireland in pursuit of the Fox. O’Keefe saw Durkin’s face prior to being shot which makes him indispensable to Scotland Yard. Detective O’Keefe agrees to go to Ireland in search of the Fox and become the house guest of an old man and his daughter on a small farm outside the town of Tubbercurry. Jim O’Dea and his daughter, Maggie, take the American into their home, but with O’Keefe comes the danger of Durkin, the Fox. O’Keefe is not only the hunter but the hunted as well. There is the additional threat of the Irish Republican Army who wants O’Keefe out of Ireland because of his affiliation with Scotland Yard.
What follows is a thrill ride of an adventure through 1990’s rural Ireland with O’Keefe matching wits with the most proficient killer in the world while also confronting the treacherous Irish Republican Army at every turn. Can O’Keefe keep Maggie safe from Durkin’s grasp and still complete his mission in killing the Fox? Or will Durkin who has never been stopped before end up killing the American detective and having Maggie to do with as he pleases? The deadly chase involving the world’s most wanted assassin culminates on a dark Irish night when Jack O’Keefe comes face to face with the Fox.
