This episode is the second half of a two-part episode; in its predecessor, "
In Purgatory's Shadow", the Dominion prepared to launch its long-awaited invasion of the Alpha Quadrant, as several Deep Space Nine officers and allies were held prisoner in a Dominion detainment facility. This episode sees Cardassia join the Dominion, drastically altering the balance of power in the galaxy. It features the return of several recurring characters and draws on plot lines from the third-season's "
Improbable Cause" and "
The Die is Cast", the body of the fourth season, and fifth-season opener "
Apocalypse Rising".
The episode premiered to almost 6 million viewers.
It is the final episode of the series where any of the main ''DS9'' cast is wearing the original ''DS9''-style uniforms. In this case, the real
Dr. Julian Bashir.

Dukat vows with the help of the Dominion to destroy all who stand in the way of Cardassia becoming a major power in the Alpha Quadrant. As Klingon ships hastily retreat from their invasion of Cardassian space, Deep Space Nine's Captain
Sisko persuades Klingon chancellor
Gowron to reinstate the alliance between the Klingons and the Federation in order to fight the Dominion. Dukat contacts Sisko, warning that he intends to conquer Deep Space Nine for the Dominion. Sisko deploys the starship ''

Back at the internment camp, the Jem'Hadar come close to discovering Garak before being overpowered by the other prisoners. Meanwhile, Worf is fighting Ikat'ika, the Jem'Hadar commander. Worf refuses to yield; Ikat'ika, impressed by Worf's determination, yields the fight. The
Vorta overseer, disgusted, orders Worf's and Ikat'ika's immediate execution. As the troops turn their
phasers toward Worf, Garak manages to activate the transmitter, and the prisoners are
beamed away to the runabout at the last second. There, Bashir sends an urgent message to DS9.
The Changeling Bashir's runabout is carrying a bomb intended to detonate inside the Bajoran sun, causing a supernova that will incinerate DS9, Bajor, and the combined Starfleet, Klingon, and Romulan forces. Receiving Bashir's message, Sisko orders that runabout destroyed. The ''Defiant'' takes the risky maneuver of engaging
