Prof. Stuart Peters is hired by NORCO physics research center and his younger brother Jory Peters drives him to California in his car. They receive a strange note from the security guard warning them that the place is doomed. On the next morning, Stuart has a short interview with Dr. Bloch that takes him to Prof. Stephanie Linden´s laboratory since they will work together. Stephanie closes Stuart in a corridor and releases an energy-being; Stuart has a heart attack and dies. Meanwhile Jory lodges in a nearby hotel and feels worried with the disappearance of Stuart. Out of the blue, Stuart returns with a pacemaker but he accidentally slips and fall into a bathtub being electrocuted by the device. Detective Sgt. Thomas Siroleo is in charge of the investigation but in accordance with the autopsy, there is something strange in the death of Stuart. Now he will investigate the mystery.
"It Crawled Out of the Woodwork" is a reasonable episode of "The Outer Limits", with the storyline of an energy monster accidentally created in a power plant and the insanity of its creator. Unfortunately the intriguing storyline is wasted by a confused screenplay. My vote is six.
Title (Brazil): "Ele Veio das Profundezas do Inferno" ("It Has Come from the Depth of Hell")
