Assigned to robbery detail, Joe Friday gets his next mission. A large amount of narcotics has been stolen from a retail chain of drugstores. His job… find it.
An addict is picked up, but questioning leads no where. When the suspect has an ax to grind with the drug gang, he gives the cops all the help they want. The job is going to be tougher than first thought. The gang is more wiley than the cops planned on. A stake out eventually turns up enough evidence to start building a case. Is there enough drug activity to bring these guys down? What about the big robbery case, can they prove who did it? Meticulous and monotonous police work finally pays off.
