this is the anti-communist, communes, "happy pills", and drugs episode. it's also the episode with leila kalomi, one of spock's few canonical romantic attachments, so from a slash point of view it's important--you'll see references to it a lot.
basically, spock cheats on kirk with thisdirty ho hippie botanist who used to have a crush on him back in school, but he does it because he's on drugs. specifically, the whole colony are telepathically linked in a big love fest by some alien plant ejaculate spores, and they feel driven to assimilate the entire crew of the enterprise... starting with spock, because the dirty ho botanist knows the only way she's going to get to molest him is if he's higher than a kite.
( kirk finds spock... high as a kite, hanging from a tree, being fondled by some ho. )
all right, this scene is veeeeery long. but it's important and stuff! ( kirk insults spock's parentage and ears in order to free spock from the evol influence of those dirty hippie commune drugs. it works. )
( a bit of innuendo, for free. )
( bonuses include spock kissing a girl. )
