With the Dominion in control of DS9 and on track to winning the war against the Federation, Sisko and his crew take a captured Jem'Hadar ship into enemy territory with a mission to destroy the Jem'Hadar's supply of ketracel-white in the Alpha Quadrant.

Alexander Rozhenko joins the crew of the Rotarran, much to the disappointment of Worf. On DS9, Tora Ziyal returns to the station where Gul Dukat intends to use her to get closer to Kira.
