Howard is mild-mannered and slightly simple-minded, with a habit of picking up teenage hitchhikers while driving his delivery routes. Sometimes the girls admit to being runaways, and if they claim to hate their mothers it drives Howard into a violent frenzy; his sister ran away from home years ago and was never heard from again, causing his desperate, addled mother to tighten her hold on him. Howard never remembers raping his victims or strangling them with wire coat hangers, though his boss does notice missed deliveries and late arrivals.

Jim Harvey is hired to guard a small wagon train as it makes its way west. The train is attacked by Indians and Harvey, hoping to persuade Aguila, the chief, to call off the attack due to Harvey's having saved his son's life, leaves the train to negotiate. He is captured and the rest of the train is wiped out except for two sisters. Escaping and showing up in town later, Harvey is nearly hanged as a deserter, but gets away. Eventually caught by the sheriff and his posse, they are attacked by Indians. This time the Indians are defeated and Aguila, captured and dying, reveals the identity of the white man who engineered the initial attack on the wagon train, just as the perpetrator rides up behind them.

When a decaying Russian satellite crashes on the island, the Professor uses a key component for a barometer. With that device, he learns that a massive wave is going to swamp the island. In desperation, the castaways lash their huts together into one structure in order to have any chance to ride the disaster out.
