Rapid aging afflicts all six colonists on Gamma Hydra IV and five members of Kirk's six-man landing party - all but Chekov. With the Neutral Zone so close, suspicion falls on the Romulans testing a new weapon, but is it? With time running out, answers are elusive. As Kirk's memory progressively deteriorates, regulations necessitate a competency hearing no one wants - the outcome of which may eventually lead the Enterprise to its destruction with all aboard.

Did You Know?


Each crew member displays different symptoms of aging: Captain Kirk suffers from short-term memory loss and arthritis, Spock becomes hypersensitive to temperature changes, McCoy becomes more moody and irritable, Galway suffers from hearing loss, and Scotty finds that he is always tired.

In the final shot, Chekov is suddenly wearing a wig instead of his natural hair. (The shot was obviously borrowed from an earlier episode.) See more »


McCoy: [to Spock] Oh, you're perfectly healthy.
Spock: I must differ with you, Doctor. I'm having difficulty concentrating, which is most disturbing, my eye sight appears to be failing, and the normal temperature of the ship seems to me to be increasingly colder.
McCoy: I did not say you weren't affected, Mr. Spock. You are perfectly healthy. That is, for any normal Vulcan on the high side of 100.

Oldies but Goodies

Try not to think too much! The crew of the Enterprise is infected by a virus that causes rapid aging after visiting a strange planet (only Chekhov manages to avoid this). There are some problems with this portrayal. First of all, the characters look really weird as they age. Secondly, even if their bodies age, why are their minds suddenly compromised. For instance, their speech patterns and vocal qualities begin to morph into stereotypical geriatric grumblings. McCoy sounds like a character out of a Mark Twain novel. The old country doctor. Kirk is doddering and forgetful. These are things that grow out of life experiences, not a few days of aging. If you turned from 40 to 80 overnight, your body would change, but your mind would continue to function as usual. As is usually the case, the conclusion is pretty much standard fair. I won't ruin it for you, but suffice it to say that there isn't much new here.
