One of the best made for TV films with a an incredible cast! Especially interesting to see Jack Lord as an F.B.I. agent (in essence he is playing a character similar to Steve McGarrett, 2 years before Hawaii Five-0!)& kudos for Edmond O'Brien's chilling performance. This film which was written by Rod Serling (written in between Seven Days in May & Planet of the Apes) was not seen for many years due to a real life incident that copied the plot of the film. This would make a nice double feature with Fate Is the Hunter.
