A young man is found savagely beaten to death in the Don Valley and Murdoch is called to the scene. It is soon discovered that the victim is Tom Meeks, a cadet at Fort York who was on a rigorous training course that teaches guerrilla warfare tactics. Murdoch decides to take a closer look at the military unit after another body is found. This victim's face was shredded in an obvious attempt to try to avoid identification. Murdoch's investigation leads to the uncovering of some very disturbing underhand medical practices that the soldiers apparently know nothing about.
