"It is the Christmas season following the 9-11 terrorist attack and McGowan's newly-appointed FBI Special Agent daughter, Caroline, assigned to the Denver office, is missing. As she is an avid lover of the outdoors, is she merely out of call range on a hiking venture in the Rockies or has she in fact been kidnapped? From out of McGowan's past resurfaces a sixties domestic terrorist, Jonas Karn, who McGowan rather ruthlessly took down years before when he himself was an FBI agent. And to McGowan's horror, Karn, obviously out for revenge, says he has taken Caroline."
