I wouldn't say that it was boring, but I have seen this kind of topic a hundred times in some 70's and 80's TV episodes. A cop killer on the loose in LA while a doctor investigates on a diphtheria epidemic. Two affairs in parallel, with nothing in common. Apparently.Robert Wagner plays the doctor - Ross!!, long before George's Clooney's character - and Greg Morris the captain of police one. That's thefirst time that I see Greg Morris- the famous Mission Impossible's Barney - in a movie, even a TV one. So, the doctor asks for help to the police force in order to locate the beginning of the disease in the city, and all people who were in contact with the DOA woman in the hospital, at the beginning of this story. The police who is very busy with its cop killer investigation.And...Guess...It appears that the killer track crosses the diphtheria deceased one.What else could we wait for in this kind of tale?
