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

Some interesting and some archaic philosophies
17 March 2014 | by (Canada) – See all my reviews

There are some good insights in this episode, like the Captain's speech about existence (how we are defined by existing among other people, experiencing things, getting old, etc). Things that make you think.

My problem is this: The idea of male and female as "universal concepts" is completely absurd! It's a human social concept which can't be applied to other animals so how could it apply to the rest of the entire universe? You don't assign genders to hermaphroditic species, do you? Incredibly illogical, old fashioned concept, considering they are just ideas we impose (men are more like "this" and females more like "that" except nothing truly defines them, because you can be and identify as female when you are more like "this" and vise versa). It erases same-sex romance and closeness (because if it's a "female" spirit it is automatically in "love" with the character) Is that the only relationship men and woman can have with each other? Could it not be brother and sister? Mother and son? Old friends? No, it has to be ~lovers~ They like to anthropomorphize everything in this show, but this time they take it farther and it ends sort of ambiguously. What happened to ambassador Hedford? What about her desires, her "existence"? I am disillusioned at the ending.
