Just a cute little episode in which Spock and Chapel head down to a moon of Vulcan, inexplicably live through a shuttle crash, and Spock is changed (by advanced beings on the far side of a tear in spacetime) into a full human -- with emotions and body odor, and everything.
It would be cute, at least, if Spock's fiancee, T'Pring, and her parents were not coming aboard the Enterprise to have a formal Vulcan engagement dinner -- and if T'Pring's mom didn't already REALLY dislike her future son-in-law.
Yes, shenanigans. Yes, matters of the heart. and, YES, there is passionate KISSY KISSY in the offing!
