Episode complete credited cast:


The Enterprise shuttlecraft, carrying Kirk, Spock, Dr. McCoy and critically ill Federation Ambassador Nancy Hedford, encounters a mysterious energy cloud which pulls them down to planet Gamma Canaris N. There they meet a castaway, a young man who purports to be Zefram Cochrane, inventor of the Warp Drive over 100 years ago. In history he had lived to be 80 years of age before disappearing somewhere in space. Apparently the same energy cloud which brought the shuttlecraft to the planet also found and rejuvenated Cochrane, making him effectively immortal. Unless Kirk can get themselves released soon, the ambassador, without vital medical treatment, will die. Written by Clive Wilson

The Most Moving and Touching of Star Trek Episodes
23 June 2008 | by (Oakland, CA) – See all my reviews

One criticism of Science Fiction, especially by non-sf people, is that not only is SF labeled as "unrealistic" (as if any movie or show can be "realistic") but it tends to be cold and emotionless. A Kleenex box might come in handy when viewing movies like "Casablanca" or "Kramer vs Kramer" but not typically for SF films. Science Fiction often deals with the wonders of futuristic technology or the fascination with the outer reaches of the universe. The invention of machines that transport molecules and the study of black holes and nebula are fascinating but not heart-wrenching. SF rarely explores the limitless realm of the inner heart. Certainly, there are times when space-suited characters might fall in love, but typically any love interest takes a back seat to the main thrust of the action.

However, there are a few notable exceptions. "Metamorphosis", a Star Trek offering from the second season, deals directly with the emotional phenomenon of love and affection without lapsing into contrived sentiment. The story even propagates the universality of love while being at its essence pure science fiction. The usual trio, Kirk, Spock and McCoy are aboard the shuttle craft with precious cargo, a woman ambassador whose negotiating abilities are regarded as the only hope in stopping an interplanetary war. Simultaneously, the woman is afflicted with an uncommon illness that needs to be treated on the Enterprise. The three enterprise crew members are on a mission to bring the woman to the Enterprise and treat her so she can return to the negotiating process that will hopefully end the conflict. Their course is thwarted when a strange energy field appears to take control of the craft and send them onto a tiny planet.

They find a human being, Cochran, who claims he was marooned there many years previous. And residing on the planet is the strange energy field that is determined not only to be a living entity but also having sentience. He calls the energy creature "the companion". At first we are led to believe "the companion" is keeping Cochran prisoner. But as the story unfolds, we learn that the companion is even more than sentient. It has true human-like emotions for Cochran.

A wonderful episode that can stand up to the best love stories with a wonderful unexpected turn-of-events. And highest marks for the two guest stars, Elinor Donahue and the late Glenn Corbett. Only the superb acting of this episode makes it work. Not to be missed, and can be enjoyed by even non-sf viewers. And it probably is the only Star Trek episode that requires a box of Kleenex!
