A spinoff of "Star Trek: The Next Generation," "Deep Space Nine" is set on a space station near the planet Bajor. This time, Commander Benjamin Sisko is in charge of a diverse crew. But unlike other "Star Trek" series, there's no USS Enterprise to help them. Sisko and the crew must fight off rival alien species who want control of Deep Space Nine because of its strategic position close to a wormhole, which allows speedy travel to the far reaches of space.

Quark gets some competition when a slick con artist opens a gambling club on the Promenade; the station suffers strange problems that are normally highly unlikely to occur.

A life form retrieved from a Gamma Quadrant planet wreaks havoc on DS9 and seems to have a strange effect on Odo.

Unaware of being used as pawns, Bashir and O'Brien attempt to eliminate a biomechanical weapon used for centuries by two warring societies.

While aboard a runabout shuttle he has stolen from DS9, Chief O'Brien records a log recounting how he returned from a mission to find his wife and friends had inexplicably turned against him.
