Former military spy Judd Ryder is walking to his D.C. home when he spots a man coming out of his row house who looks like him and is wearing his clothes. As Ryder slows to follow, the imposter is killed in a hit-and-run that's no accident. Was the man the intended victim, or was it Ryder himself? Soon Ryder learns that the key to the mysterious events of the past and to his double's murder is an infamous Cold War assassin, the Carnivore. Two of the last people to see the Carnivore were Ryder and CIA trainee Eva Blake, and someone is using them to lure him out.
