Unusual animal deaths at the Lincoln Park Zoo are the first sign that Chicago has a new resident. The killings spread to humans, with each of the victims having been drained of bone marrow. Kolchak and the police are witness to a strange invisible force that escapes with 10 tons of lead ingots, and leaves piles of black goo in its wake. The goo is composed of bone marrow and digestive acids. Combining this information with the widespread theft of electronic appliances, Kolchak comes to believe that an alien electromagnetic creature is on the loose. Using a compass, he tracks the being to a planetarium, where it is consulting star maps in an attempt to locate its position. Kolchak manages to drive the creature off with the high-pitched noise of his camera flash-recharger, and follows it to its spacecraft for a final confrontation.
Guest Cast: Mary Wickes (Dr. Bess Winestock), James Gregory (Captain Quill), Dick Van Patten (Alfred Bindle)
Notes: X-Files creator Chris Carter has often credited The Night Stalker as his inspiration for his own series. This episode, with its presence of mysterious government agents and organized coverup, is very similar to several early X-Files/UFO episodes. The alien(s)’ invisible presence is effectively conveyed by first-person camera work, a blowing wind, and strange sound effects.
