The Exodus, Pt. 1

S3 E16: The Sliders land in a city besieged by looters, as defense sirens wail. They come across a vagrant, who blames the Russians. Apparently, the Cold War has not ended in this dimension. Suddenly, a car races around the corner, flipping and exploding. The Sliders try to rescue the driver, who mumbles something about a trajectory being wrong. As he dies, the Sliders notice blood seeping from a gunshot wound. Arturo (John Rhys-Davies) recognizes the man as Dr. Jariabek, a noted cosmologist.
