Brilliant grad student Quinn Mallory has created a device that opens a wormhole to an infinite number of parallel universes where history has taken different paths, some subtly changed and other radically different. Quinn's test trip goes awry, stranding his physics professor, Arturo, his friend, Wade, and bystander Rembrandt in parallel San Francisco's, "sliding" from one alternate reality to another, unable to return home.
