Spock has been acting irrationally. Erratic behavior, emotional outbursts, the works. He requests a leave of absence on Vulcan; Kirk wants to comply but pushes Spock for his reasons. What Kirk learns is that there’s a whole lot more going on under the seemingly impenetrable veneer of Vulcan logic and stoicism — there’s a volcanic (pun intended) rage that threatens to erupt every seven years at the time of Pon farr. Kirk offers to help Spock during the associated ritual, only to learn that he’ll have to fight his friend and first officer to the death.
