A string of murders leads the OSC to Boston which is Creegan's hometown. A priest, Father Bob, is in confession with a man when the man tries to kill him. The man, dubbed the "Blade Runner", has committed 5 other murders. Bob tells the detectives all that the "Blade Runner" told him in the confession booth but, Brance doesn't believe because of her past experiences with Catholicism. The neighborhood watch had received earlier a photo of on the victims, by email, and another comes with a message saying he won't stop until the ringing in his head stops. Creegan thinks it's a guy with tinnitus so they arrest a medic with tinnitus, Sammy Rashaad, who was also at 4 of the murder scenes. Meanwhile Creegan visits his old neighborhood. Rashaad is released on the account that his has alibis for each murder. Creegan talks to Bob again and realizes they're after a mailman with a thing against faiths. They search Fred Stentz place and find that he is indeed the "Blade Runner". Branca, on the other hand, goes to Bob only to find him knocked out. Stenz almost kills her if not for Creegan's intervention.
