Stardate not given: The Federation and the Klingon Empire are now at war, and the only way to stop it is to prove that Gowron, the leader of the Klingon High Council, is a changeling. To expose the spy, Sisko and three officers – Worf, O’Brien, and a now-human Odo – must infiltrate a Klingon ceremony in disguise, and activate devices which will cause the changeling to lose its shape. But getting there, and staying undetected long enough to accomplish their mission, is much easier said than done…

Notes: Kira blames her pregnancy on Bashir in this episode, a gag which puts a crack in the fourth wall as Alexander Siddig really was the father of the child Nana Visitor was expecting at the time.
