In a world where San Francisco serves as a prison, two new sliders join the regulars. One is a woman, Michelle, whom Quinn saved from a beating. The other is her savage boyfriend, Sid, who followed them. The Sliders are fitted with buddy bracelets which are used in a buddy system of justice. If one "buddy" commits a crime then the other is punished. Of course Quinn is responsible for Sid's predictable actions. The timer becomes a hot commodity for both prisoners and guards who want to escape an earthquake doomed city.
