Kirk orders stepped-up security, but that only results in some of the crew - including Scotty and Chekov - instigating a massive bar brawl with the Klingons.

In the meantime, Sargon and Thalassa, in the bodies
of Kirk and Mulhall, fall in love all over again. One way or another, though, the humans' bodies must be vacated since their metabolism is incapable of withstanding the levels of activity taken on by Sargon and the others.
