DS9 is center ground as the Klingon conflict intensifies. Gowron tries to persuade Worf and the Defiant rescues a Cardassian convey carrying Gul Dukat.
Kira assists Gul Dukat, now in command of a freighter, to stop a Klingon Bird-of-Prey that destroyed an outpost with a joint Bajoran and Cardassian delegation.
Garak, Worf, and Bashir search for Enabran Train after intercepting a distress call from the notorious Cardassian. Meanwhile, Dukat visits Ziyal on DS9.
As Cardassia forges an alliance with the Dominion, Worf, Bashir, and Garak plan an escape from captivity with the help of fellow-captive General Martok.
To prevent additional Dominion reinforcements, DS9 mines the wormhole’s entrance, escalating tensions between the Federation and Dominion… leading to a climatic ending.
