Kira and Bashir are returning from the opening of a hospital on New Bajor in the Gamma Quadrant. Just as they're to enter the wormhole, a sudden problem arises. Kira is able to solve it, but when they arrive in the Alpha Quadrant things seems to have changed. Deep Space Nine is once again orbiting Bajor and the runabout is entered by Klingons, who excuse themselves when they see Kira. It soon becomes clear the two have arrived in alternate universe. Klingons, Cardassians and Bajorans have formed an alliance against Earth and humans are forced to do slave labor on Deep Space Nine. The station is led by intendant Kira. She speaks of a person named 'Kirk,' who traveled from the other side earlier. While Bashir is sent away to ore processing, intendant Kira seems to really like her other self.

Did You Know?


After "Crossover" aired, there was a great deal of discussion about how sexy and alluring Nana Visitor was as the Intendant, with the costume she wore garnering a great deal of attention. According to costume designer Robert Blackman, the general consensus amongst fans was that it was the revealing nature of her costume which gave Visitor this new level of seductiveness. See more »


Benjamin Sisko exists in the Mirror Universe. Given what is revealed in the first story arc of Season 7 about the regular Sisko's parentage, this is highly improbable. See more »

"Mirror, Mirror...Part 2"
19 December 2014 | by (Bradenton, Florida) – See all my reviews

This is a sequel to an episode from the original "Star Trek". It's a follow-up to "Mirror, Mirror"--one of the very best of the old episodes. In this old episode, a landing party beams back to the Enterprise--only to discover it's AN Enterprise from a parallel world. This world is much like the original one except that the Federation is a force of evil and the Enterprise crew advance in rank through betrayals and assassinations! It's an incredibly cool episode--and a must-see for fans.

"Crossover" begins with Major Kira and Dr. Bashir arriving at Deep Space 9--except that it's not their Deep Space 9. Instead, it's from the same parallel world visited by the Enterprise. Interestingly, it shows the results of the previous contact has been drastic. The 'nice' crew members apparently did something to soften the evil Federation-- so much so that now the Cardassians and Klingons are the dominant force in the quadrant--and human are on the run! And, interestingly, the evil Major Kira is a high official in this evil empire--and a sexy official with attitude!

Too often the Trek shows are extremely nice and astoundingly perfect--often TOO perfect. With episodes like this one and the Maquis, you finally see a different sort of future--a dark, twisted and darkly funny one. Well worth seeing, though the original episode is a touch better.
