While investigating and scanning an uncharted planet, the Enterprise and its quadrant of space are subjected to a violent force that seems to cause a 'blinking out' of everything near them. When the scanners resume, where once there was no life on the planet, now there is one life sign. Kirk, Spock and a security force beam down to investigate and find a man named Lazarus who collapses and is brought aboard the Enterprise for treatment. To complicate things further, the initial phenomenon almost totally drained their dilithium crystals. Starfleet and Kirk suspect this phenomenon could be a prelude to invasion. While interrogating Lazarus he tells Kirk that he's locked in a struggle with another being who is 'anti life' and is behind the phenomenon. The disruptions continue to occur and the ship's situation grows worse. Written by

Along with Star Trek: Friday's Child
(1967), this is one of the only two episodes where outdoor planet scenes were filmed both on Desilu Stage 10 and on location (both times at Vasquez Rocks). Originally, all planet-side scenes were scheduled to be filmed on location, but due to the turmoil during production, director Gerd Oswald
couldn't finish shooting at Vasquez. Matt Jefferies and the art department prepared a spot on Stage 10 which could accomodate the missing "alternate universe" sequence. See more
When the fire starts in engineering, and the assistant engineer drags Masters out of the room, when they are almost to the door the smoke in the room is still relatively light, and there is not enough of it to obscure vision, but less than 3 seconds later when the door to the corridor opens, the smoke is so thick that it is not possible to see through it, a solid wall of smoke.
