Waltz (Star Trek: Deep Space Nine)

"Waltz" is the 11th episode of the sixth season of the television series Star Trek: Deep Space Nine, the 135th episode overall.

Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station near the planet Bajor, as the Bajorans recover from a long, brutal occupation by the imperialistic Cardassians. This episode is part of the Dominion War storyline, in which the United Federation of Planets is at war with the Dominion, an aggressive empire that has already absorbed Cardassia.

In this episode, former Cardassian leader Dukat, once the prefect of Cardassia's occupation of Bajor and then the orchestrator of its alliance with the Dominion, has been captured by the Federation and is en route to be tried for war crimes; he and Deep Space Nine′s captain Benjamin Sisko end up marooned together on a deserted planet, where Sisko must rely on the increasingly unstable Dukat for his survival.
