When physics student Quinn invents a way to travel to parallel universes, he takes his friends Wade and Maxmillian along for the ride. But they accidentally pick up another passenger along the way.
Cissy brings one of her friends, a pregnant woman named Kathy, home to visit everyone while Kathy's husband is out of town.
The Sliders go to a world where time moves slower, and Quinn must protect the younger version of himself.
The Sliders arrive in a world about to be destroyed by a star emitting intense radiation, and can save only some of the people by sliding them into other universes.
One of the Sliders is lost during the mission to save a doomed world, while Arturo and Wade battle an egomaniacal military commander over who will be rescued.
