With the war between Klingons and Federation intensifying, Sisko must make a plan to expose Gowron as a changeling. Odo is still having trouble with becoming a solid.

The crew is forced to retreat in a crashed Jem'Hadar ship after an attack by the Jem'Hadar. They get the feeling there's something very important about this ship.

While Worf helps Quark to pursue his former wife Grilka, O'Brien and Kira grow uncomfortably close to each other.

Jake, reporting from the front lines, sees what war truly is.

A Pah-wraith possesses Keiko's body and forces Chief O'Brien to complete a task, or Keiko'll be killed.

Sisko tells two men from Temporal Investigations how he and his crew went back in time to when Captain James Kirk of the first Starship Enterprise exposed a Klingon spy with the help of Tribbles.

While vacationing on Risa, Worf and Dax meet a group of fundamentalist protesters who claim that the Federation has gone soft.

Sisko, Dax, Odo and Garak find themselves in the past when the Cardassians controlled the station, and a crime that Odo investigated may be the key.

On their way to answer a warrant, Odo and Quark crash, and must put aside their differences to survive and signal for help.

Sisko begins having visions that may show him how to best help Bajor, but they're killing him.

A mysterious assassin begins wiping out all the members of Kira's old resistance cell.

The discovery of an infant Changeling gives Odo a chance to correct what he sees as the "mistakes" in his upbringing. But as Starfleet's pressure for results grows, he has to turn to his "father," Dr. Mora.

When the traitorous Eddington returns, Sisko will go to any lengths to capture him.

A coded message from the Gamma Quadrant leads Garak to believe his mentor, Enabran Tain, is still alive. He and Worf seek him out, only to discover something much worse: a Dominion invasion fleet poised to attack the Alpha Quadrant.

The station readies for a Dominion attack. Worf and Garak meet some unexpected friends in a Dominion Prison camp.

Dr. Bashir is selected to be the model for the next-generation of Emergency Medical Hologram (EMH). But he balks when his parents are invited to the station to be interviewed by the EMH programmer, Dr. Zimmerman. There is a dark secret in his family that he's afraid that his parents will reveal.

Odo becomes romantically attached to a woman working with the Orion Syndicate.

Quark must wrestle with his conscience when he becomes involved with arms merchants.

When a Cardassian official, who thinks of Kira as his daughter, is dying, he agrees to reveal all he knows to her. But the experience dredges up Kira's memories of her own father's death.

Quark doesn't know whether to be panicked or overjoyed when he learns that his mother is the new lover of the Grand Nagus.

Dax and Worf accompany Martok on his first command since being held by the Dominion. But the ship they are given hasn't seen victory in months and the crew is near mutinous.

The DS9 crew discovers a small colony on a remote world that was originally populated by them 200 years earlier due to a time-travel accident with the Defiant. The current colonists lives depend on making sure that accident happens again, even though they've now forwarned the crew that it will happen. Each crew member needs to decide if they are willing to give up their lives on DS9 in order to preserve the history of the colony.

Driven to desperation by the Dominion, the Maquis launch a massive bio-weapons strike towards Cardassia. Sisko must trust the traitor Eddington to try to stop them.

While salvaging components from DS9's sister station, the crew run afoul of a "surprise" left behind by the Cardassians.

Jake and Nog go through hell and high water, from participating in an auction to dealing with the Dominion, to receiving a Willie Mays baseball card, all in order to cheer up the war-fatigued Captain Sisko.

Deep Space Nine prepares for a Dominion attack.
