Too talky, turtle-paced, and just plain boring is this story of a killing on the New York subway system. The killer rigged the wiring to cause a powerful enough shock to do someone in. As everyone on the train is being quizzed, the audience just wishes the end would come soon, and after
the third round of questioning, Holt finds the killer. Finally, for what it's worth, the action takes place entirely within the subway system.
