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?


In The World of Star Trek, William Shatner relates that he endured an excruciating make-up session for this episode - all for nothing, because the shooting day was just about to end. The producers caught his exasperation in an infamous blooper, wherein he declares, "Robert H. Justman, I'm going home now, after spending three hours putting this [expletive deleted] make-up back on - and it's your fault!" See more »


Early in the episode, Commodore Stocker consistently addresses Captain Kirk as "Sir", even though it has been established in previous episodes (and in naval protocol) that commodores outrank captains. See more »


McCoy: Anytime you're ready, Mr. Spock.
Spock: I am quite ready now, Doctor.
McCoy: Because of your Vulcan physique, I've prepared an extremely potent shot for you. However, I thought you'd might like to know that I've removed all the breakables from sickbay.
Spock: That is very considerate of you, Doctor.

What a Drag it is Getting Old
3 October 2007 | by (Vulcan) – See all my reviews

The Enterprise is shuttling a Commodore back to the star base he commands and enters orbit to make a routine check on a scientific expedition. They find that the scientists have aged at an alarmingly accelerated rate and are senile and on the brink of death. Soon the entire away team, with the exception of Chekhov, are experiencing the same symptoms, and Kirk is actually becoming senile. As things get worse, the Commodore takes over the ship and blunders into the neutral zone.

The problem with this episode is that it started out with a poor premise and never really improved its plot at all. It is predictable, and even recycles a plot device from the first season in the most obvious manner possible. The episode is decently directed scripted, shot and acted. But it started out with questionable material and those involved could only do so much to improve upon what they were given.
