Shock effects and horror movie tropes dominate this Climax! Episode. Fortunately, Robert Preston is so authoritative and strong in his role as a police detective tracking down a mad killer that the show overcomes these hokey weaknesses,
Porphyria is exploited as the central plot element, a hereditary disease that has a father from Brazil out for revenge against a doctor he thinks is responsible for his daughter's death. Diana Lynn is the doctor's wife, who is so shocked by her husband's murder that she becomes obsessed with revenge herself.
Lynn has a field day of displaying multiple personalities over the course of the hour, ultimately winning in a moral crisis, aided by straight-arrow Preston. The dramatics here are hyper, and overall it becomes clear that this Live TV series is built around ampng up everything to a fever pitch, including violence not usually tolerated on television by the censors.
