Weird. The Kai visits the station and wishes to go through the wormhole. Sisko, Bashir, and Kira join her in a runabout. Soon after they crash land on a planet, and the Kai dies. They soon discover that this planet has two war torn factions. The Kai returns to life, and after a little battle so do everyone who died in that battle.
The planet is actually a penal colony and these people have been punished with some life restoring nanites or something that will keep them forever alive to battle, and removing them from the planet would kill them. So the Kai has to stay to live, and she wants to help the people.

It is a lame episode.
