The crew encounters plastic puke monsters that threaten civilization as they know it.
Following a string of planets that have gone mad and died, the Enterprise gets to the last one on the list - the one where Kirk's brother lives. When they arrive they find that a ship is on a crash course toward the sun! They try to save it, but whoever's inside is intent on following through. Over the communication channel, he says "I'M FREE!" and dives into the massive star.
They return to the planet to find the civilization has gone mad. They seem to want to hurt the landing party, but at the same time they're warning them to get away. After phasing the welcoming committee, they rush to Sam's house (Kirk's brother), and find him dead on the ground with his wife screaming that something is trying to get them. The son of Sam is also laying on the ground, but he's still alive, so Bones takes him and the wife back up to the ship. And now it's time to figure out what the heck is going on.
|She obviously can't handle your sexual magnetism, Jim.|
Except it caught him by surprise. While Spock is still trying to figure out what's going on, the parasite's infection makes him try to take over the ship and Bones is forced to sedate him. Eventually Spock wakes back up, though, and appears to be completely under control. He says that pain is a thing of the mind and that, as a Vulcan, he is able to keep it under control. With this in mind, he should be able to go back down to the planet and bring back a specimen without risk of being infected again.
|Dude, is this guy serious right now?|
Spock goes through the test, comes out, and says the pain is completely gone, but he is quite blind. And that's when Bones figures out that he didn't have to use the full spectrum of light. He kicks himself for not thinking that just infrared light could work! Well, at least now they can set up a bunch of satellites to bombard the colony with infrared light. So that's what they do and the colony is saved! YAY! And then Spock walks onto the bridge... and he can see! Turns out Vulcans have a second pair of eyelids due to the brightness of the Vulcan sun.
|Spock at the end of pretty much every episode.|
This was a pretty great episode. Except for the fact that they killed off Kirk's brother and he seemed to have no reaction to it at the end when the immediate danger is out of the way. I assume the funeral took place off screen? And Kirk's brother's death doesn't have any affect on him from this day forward? Meh. Besides that, the rest of the episode was good. It's the first mention of a hive-mind type of creature.
