A series of sexually oriented murders that are identical, except that the killer appears to be both male and female, draws Scully and Mulder to an Amish-type community of people who may be alien in origin.

Mulder reluctantly accepts a new partner, Agent Alex Krycek, and they investigate the deaths of several Green Beret soldiers who participated in a sleep deprivation experiment during the Vietnam War.

A lightning strike transfers Clark's superpowers to a classmate, who begins to abuse his new abilities. Meanwhile, Lex thinks he has proof of Clark's superpowers.

Mulder and Scully investigate the possible return of an executed prisoner who vowed to avenge his death.

Clark is staggered by his newfound ability to see through solid objects with X-ray vision, especially when he witnesses Lex Luthor commit a bank robbery. Elsewhere, a shape-shifting teenager threatens Lana.

After rescuing Lana from the eye of the storm, Clark discovers it has dropped the spaceship into the fields, burying alive his father and the unscrupulous reporter who discovered his secret.
