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

When Lazarus sabotages the Engineering Panel, the electrical plugs he switches around are actually Dual Binding Post Plugs, very common when this show was made in the 1960s and still in use today. See more
When Lazarus leaves his bed in the sickbay at around the 30 minute mark, the bed continues to broadcast his heartbeat. Indeed, when he starts to have an attack, his heartbeat speeds up. Normally, the sickbay bed can only read a person when he is lying on it; the sound should have stopped as soon as he stood up. See more
