The Sliders must wrestle themselves away from addiction after they land on a world that encourages the use of drugs and narcotics.

After the Sliders check into a haunted hotel, they become ghosts trapped in a howling vortex between two parallel worlds.

The Sliders land on an alternate Earth that has no life, a toxic atmosphere, two moons and a labyrinth filled with Kromaggs.

An injured Rembrandt falls in love with his doctor, who is eager to follow him because of her secret past as a Kromagg collaborator.

The Sliders arrive on a world where World War II never took place and fascists rule California and are making headway into the rest of the United States. Rembrandt is abducted.

In a world where tattooed humans are hunted for sport by the new Kromaggs/Human half-breeds, the Sliders attempt to save a captive Colin. Rembrandt is poisoned and needs the help of his enemy to survive.

An outrageous talk show host rules the airwaves of the world the Sliders enter, and Quinn goes on his show to contact the others.

After saving a human woman and her child from the child's Kromagg father, the Sliders discover the child cannot survive on Earth.

The Sliders land in a world divided into Onliners, people who subsist on the Internet, and Offliners, people who repudiate the technology.

Maggie's double leaves her stranded on a militarized world, where she is united with her dead husband's double.

After a computer genius turns the sliders into computer-generated images, he deletes Maggie, who must be retrieved from a junk file directory.

Colin is wounded and left for dead in a Wild West Earth, and the others must face an old foe.

The Sliders arrive on a world where clones are harvested for spare body parts. Quinn's double is blinded in a lab accident and when Quinn tries to help, he is mistaken for a clone. Meanwhile, the others inadvertently rescue the clone, which Colin tries to teach the importance of family and sacrifice.

The Sliders arrive in what is literally the happiest place on Earth. But in this small community, a little girl witnessed her grandfather leap into a mysterious chasm and begins to feel an overwhelming sorrow. Worse yet, it soon spreads to Rembrandt and Maggie.

A rough slide separates Quinn and Maggie from Rembrandt and Colin for a brief time. Soon after they reunite, Quinn and Maggie become seriously ill and appear to be dying of old age. Unable to help them themselves, Rembrandt and Colin will have to rely on someone claiming to be Quinn and Maggie's son.

With nearly a month until their next slide, the Sliders find themselves extremely bored on a dull world. While the others get jobs, Rembrandt dives into a sci-fi book that bears more than a passing resemblance to their lives. When the Sliders track down the author, they learn he came from Quinn and Colin's home world.
