After a desperate prisoner escapes from the Tantalus Penal Colony to the Starship Enterprise demanding asylum, Captain Kirk launches an investigation into the alleged mistreatment of the colony's inmates by its revered director, Dr. Tristan Adams. Accompanied by Dr. Helen Noel, Kirk beams down to Tantalus to learn the truth, only to discover that Dr. Adams is running the colony like a nightmarish chamber of horrors. For the second “Star Trek” episode in a row, Captain Kirk comes face-to-face with a mad scientist. And like the episode before it, “Dagger of the Mind” is a thought-provoking, deeply-engaging, well-written and superbly acted episode that also features a “Star Trek” landmark — the first appearance of the Vulcan Mind Meld.
