After eighteen months, the sliders finally return home. However, all is not as it seems, particularly with Professor Arturo.
In a world that greatly resembles the Sliders' place of origin, everyone must decide whether to stay or leave the doubles of their loved ones in order to find their way home. Professor Arturo's double steals the timer and claims the invention of Sliding as his own. A physical struggle ensues among the two professors.—Mark D. Snyder
