"The Way to Eden" is the twentieth episode of the third season of the American science fiction television series Star Trek. The episode was written by Arthur Heinemann, based on a story by Heinemann and D. C. Fontana (using the pen name "Michael Richards"). It was directed by David Alexander, and first broadcast on February 21, 1969. In the episode, the Enterprise is hijacked by a hippie-like group obsessed with finding a mythical paradise. Plot The Federation starship Enterprise is in pursuit of the stolen space cruiser Aurora. In trying to escape, the Aurora overloads its engines and its six passengers are safely beamed aboard the Enterprise just as the Aurora explodes. The group consists of Tongo Rad, son of the Catullan ambassador; Irina Galliulin, an acquaintance of Ensign Chekov; Dr. Sevrin, a noted electronics, acoustics, and communications researcher; Adam, a musician; and two other women. In responses to Kirk's questions, Dr. Sevrin says their destination is the planet "Eden", which Kirk responds is a myth. The group refuses to co-operate with Kirk, but are impressed by First Officer Spock, who is familiar with their social movement. They are persuaded to go to Sickbay for a medical examination which reveals the party to be in good health, except for Sevrin, who is an asymptomatic carrier of a bacterium. Sevrin is quarantined in the brig. He admits to being aware of this, and believes it to be a product of artificial environments, and tells Spock that the planet Eden will somehow "cleanse" him. Spock attempts to reason with Sevrin and offers to help him find Eden in exchange for his cooperation, but concludes that Sevrin is not sane. The rest of the group plan to take over the ship. After putting on a music concert including Spock, during which Rad frees Sevrin, the group takes over Auxiliary Control and puts the Enterprise on course for Eden. On arrival at the planet, Sevrin renders all Enterprise crew unconscious with an ultrasonic frequency broadcast through the intercom. When the crew regain consciousness, they discover that Sevrin and his followers have stolen a shuttlecraft. Kirk deactivates Sevrin's sonic device, and then joins Spock, Chief Medical Officer Dr. McCoy, and Chekov in a search for the group. The planet surface is lush and beautiful. However, all the plant life secretes a powerful acid, as Chekov discovers when he touches a flower. The team soon finds
