Nominated for 28 Emmys, including several for Outstanding Visual Effects, Star Trek: Deep Space Nine continues the rich tradition of the original 1960s Star Trek franchise. Created by former L.A. police officer Gene Roddenberry, the Star Trek TV series morphed into a franchise famous for the unprecedented fanatical devotion of its audience. Lasting only three seasons during its original network run, Star Trek struck gold with its syndicated reruns, launching a number of motion pictures featuring the original cast as well as novels, comic books, collectibles, and reams of Star Trek-related memorabilia. Following on the heels of Star Trek: The Next Generation (1987), the first Star Trek series spin-off of the original, Star Trek: Deep Space Nine foreshadowed additional spin-offs - Star Trek: Voyager (1995), and Star Trek: Enterprise (2001). Sporting an entirely new cast and crew from its two predecessors, the show focuses on a particular system administered by the Federation instead of the usual Star Trek mission of "exploring strange new worlds"

Star Trek: Deep Space Nine follows the exploits of the Starfleet crew aboard an abandoned and gutted Cardassian space station orbiting the planet of Bajor. In the aftermath of Cardassian occupation, the Bajorian government invited the Starfleet to oversee the reconstruction of the space station. Deep Space Nine quickly transformed into a teeming city of commerce and a hub for travel (similar to Babylon 5) thanks to the discovery of an unknown wormhole nearby. But the wormhole leads to the Gamma Quadrant, realm of the feared Dominion alliance, which views the wormhole travelers as a threat to its totalitarian grip on power. As such, the Dominion launches an attack against the Federation and its Klingon allies. The subsequent and ongoing war is the basis for Star Trek: Deep Space Nine

Capt. Benjamin Sisko (Avery Brooks) is credited with discovering the wormhole, and he oversees the crew of Deep Space Nine as they wage battle to preserve the Federation. Ironically, his colleague, Constable Odo (Rene Auberjonois), is a Changeling - an alien race of "shapeshifters" who lead the Dominion's united front. Together with the rest of the crew aboard Deep Space Nine, they struggle with internal and external conflicts that threaten to destroy their very way of life

The Star Trek: Deep Space Nine (Season 7) DVD features a number of exciting episodes including the season premiere "Image in the Sand" in which Sisko searches for the Bajorian Orb of the Emissary which will allow him to reopen the now closed wormhole to Gamma Quadrant. In his absence, Kira commands Deep Space Nine while Sisko sees images of his mother's face in the sand Other notable episodes from Season 7 include "Covenant" in which Kira is pressured to join a cult religious group when she is accidentally teleported to Empok Nor, and "Extreme Measures" in which Dr. Bashir and Miles go to great lengths to discover a cure for a dangerous and life-threatening virus
