Dax is going out with a Dalamite captain (Kira is squicked because Dalamites have transparent skulls). A Cardassian ship explodes while leaving the station.
Dax comes up with a theory indicating sabotage, and O'Brien starts scanning the debris to confirm the theory. One of Sisko's old pals, Cal Hudson, turns up (he's the attache to the Federation colonies in the demilitarized zone) and they discuss Dax and the colonies.
A Vulcan, Sakonna, approaches Quark with a business proposition and he asks her to dinner to discuss it. Meanwhile, some random guy gets ambushed by some other random guys.
Sisko finds Gul Dukat in his quarters
Back in the B plot, Quark has dinner with Sakonna. This B-plot is so unimportant that it's not mentioned at all on the startrek.com episode page. Sakonna wants to buy weapons.
In the demilitarized zone, Sisko and Dukat find an argument between Hudson and Gul Evek over the attacks. Evek has the confession of William Samuels, who supposedly blew up the Cardassian ship at the start of the episode. Unfortunately, Samuels himself "committed suicide" soon after. This leads to one of the colonists physically attacking Evek.
Sakonna is somewhat urgently wanting her weapons so she can get off the station.
Sisko and Dukat return to DS9, where O'Brien says he's found that the implosive device which destroyed the Cardassian ship was Federation in design. Kira and Sisko have an argument over what they should do. Meanwhile Sakonna and some colonists kidnap Dukat.
After Sisko has finished exploding, they attempt to trace Dukat. A message from the demiltarized zone takes credit for the kidnapping - they're calling themselves the Maquis. Why, hello build up to Voyager. Sisko takes a team into the badlands and they beam down to an unfeasibly tropical asteroid, where they're captured by a band of Maquis lead by Cal Hudson.
