Landing in San Francisco, the Sliders are amazed to find the city in ruins; not due to a Kromagg attack, but to complete abandonment. They discover that everyone has disappeared. However, Quinn soon realizes that animals are still inhabiting this earth when he is attacked by mongrels. Maggie scares the dogs off with the help of a shotgun she finds in a pawn shop, and the Sliders head to Quinn's home. They find it empty like everywhere else. The difference: apparently the Quinn of this world was even more intelligent, garnering award after award. While Quinn continues to search the house, Rembrandt and Maggie wait outside -- and are approached by the disheveled Quinn of this world. At first frantic -- he has been totally alone -- he calms down enough to explain that he built a machine that, when he threw the switch, wiped out every human being on Earth.
