A Vulcan woman, T'Irayne, does not wish to be married, and fights for her freedom. A rather different perspective on pon farr than the usual.
In the end, the two decide to get to know one another better, with the possibility that they will choose to be married, in the future.
As Spock with Kirk, so too does T'Irayne bring her close friend and captain, Mary Jane Watkins (captain of the U.S.S. Hood), to the ceremony.
