“Star Trek: Deep Space Nine” Episode Guide by Suzanne

FIRST SEASON

Emissary (pilot episode) The space station, Deep Space Nine, set in a sensitive area near the planet Bajor, is now run by Starfleet, since the ruthless Cardassians have left. The Bajorans are recovering from a long occupation by the Cardassians, but there’s still a lot of tension between them. Captain Sisko sets out to repair the station and help the Bajorans, but then he discovers that some mysterious ghostly beings live inside the nearby wormhole that connects to the Gamma Quadrant (which has not been explored). He’s aided by other Starfleet officers Dr. Bashir, Major, Kira Narees, Chief O’Brien, Commander Worf, first office Dax and security chief Odo. Sisko, a widow, is also raising his young son, Jake. They have to contend with the conniving Ferengi on the space station, as well as many travelers (some of whom are not friendly).
