Sliders

Brilliant grad student Quinn has created a device that opens a wormhole to an infinite number of parallel universes where history has taken different paths. His first test trip goes awry stranding his physics professor Arturo, his friend Wade, and bystander Rembrandt "Crying Man" Brown in parallel San Francisco. Now, this foursome of Sliders must travel from one alternate reality to another in the hope of somehow finding their way home.
