 A highly decorated NYC Paramedic, Gideon(William Atherton), is on an "angel of death" killing campaign targeting homeless winos. No one suspects a thing as he drugs them and it appears they die from heart attacks. A Skid row mission worker becomes aware that someone is doing this as his latest victim, though certified dead from a heart attack, was known to him to be in perfect health. He calls in McCall to find out who it is and stop them. It turns out there is more to Gideon s murder episodes than meets the eye as it becomes clear he suffers from an advanced state of Combat fatigue after 20 years of service.
