The Sliders track Rickman to a superstitious town. Their search is further complicated when Quinn and Maggie are captured by natives living in a mysterious fog. There, Quinn runs into someone from his past â- himself.

Two old cold war naval foes, whom had once collided their war ships together before as enemies, now have collided their ships again as allies while preparing to participate in war game exercises. Harm and Mac are assigned to monitor the Russian ship as observers, while a Russian team, familiar to Harm, act as observers on the US vessel. However, both observing teams find that both Captains are more than ready to continue their cold war conflict. Worse, one Captain appears ready to sacrifice everything and everyone to be the final victor of the war between the two.
