When a man hears gun shots in his neighbor's home and calls 911, Detectives Briscoe and Curtis find themselves investigating the murder of a wealthy man and his very young daughter. The wife and mother of the deceased seems to know a lot more than she lets on. District Attorneys McCoy and Carmichael hit a snag in the case when important evidence cannot be obtained because of unusual circumstances.
The Riddler was shown in the opening credits but never appeared in any of the episodes because Hanna-Barbera licensed him for "The Superfriends".
