Moving from the Fox network to the Sci-Fi Channel for its fourth season, Sliders picks up the action some three months after Season Three left off. After innumerable "slides" through various wormholes taking them from one parallel Earth to another, extradimensional travelers Quinn Mallory (Jerry O'Connell) and Maggie Beckett (Kari Wuhrer) have finally arrived at Quinn's homeworld, Earth Prime--only to discover that the planet has been enslaved by the fascistic Kromagg Dynasty which Colin had briefly encountered two seasons earlier. The Kromaggs have captured fellow "sliders" Rembrandt Brown (Cleavant Derricks) and Wade Wells, enslaving Remmy and placing Wade in a breeding camp from which she will never return (actress Sabrina Lloyd) had left the series in 1997). More shocking news comes Quinn's way when, upon being reunited with his mother (Linda Henning), he is told that he was adopted--and that his actual homeworld is Kromagg Prime. Joining an underground resistance movement in hopes of liberating Remmy, Quinn and Maggie simultaneously embark upon an odyssey to find Colin Mallory, the brother Quinn never knew he had...until now.
