The Lorelei Signal

The Enterprise enters a sector of space where vessels have been reported missing every 27 years. While in the Taurean system signals begin to affect the male crew, causing them to hallucinate. Kirk, Spock, and McCoy beam down to the source of the signals. After arriving on the planet they are taken prisoner by a group of beautiful women. The landing party begins to age rapidly as a result of life-draining headbands they are forced to wear. On board the Enterprise, Uhura has taken command due to Scotty's irrational behavior. Uhura orders an all-female landing party to transport down to rescue the men. The landing party eventually beams the male landing party back up to the ship just in time to replenish their life-force.
