Episode:223
Crossover

Jack's Rating:

Kira and Bashir accidentally cross to the Mirror Universe, where a Klingon-Cardassian alliance rules. A century before, James T. Kirk had made a similar crossover, affecting human and galactic history. Terrans are slaves on the station.

DS9 goes back to the original mirror universe so well here that my only complaint was that the episode ended....
