 Kira has found out a Valerian ship, known for transporting dolamide, used in Cardassian weapons, to Bajor, is about to dock at DS9. She is convinced the Valerians are still trading the stuff and wants to deny them, but Sisko disagrees with her. He is only prepared to let Kira take action when she provides evidence. Meanwhile a Klingon ship returns early from a mission in the gamma quadrant. It explodes in front of the station and a Klingon who managed to beam aboard dies almost instantly. Odo tries to find out what happened, but after he experiences some weird pain that causes his head to split in two, he notices something has happened to the crew. All over the ship people seem very adamant to choose sides between Kira and Sisko. It looks there s a mutiny as Kira has plans to get rid of Sisko and tries to get as much support as possible.
