 This two-hour episode, actually Parts 1 and 2 of three (in the NBC reruns, they were shown as two 90-minute episodes; in syndication, they are three one-hour episodes), is a close retelling of the Son of Sam case, with Albert Colvin (James Stephens) as a serial killer who hunts down and shoots beautiful women while taunting reporters by phone. This and other Eischied episodes makes extensive use of location filming in New York, a rarity for television series of the time.
