Genre: Mystery

A series of sexually-oriented murders, which are identical except that the killer appears to be both male and female, draws Scully and Mulder to an Amish-type community of people called the Kindred.

An old Oxford girlfriend of Mulder's asks for his help on an international case concerning the unexplainable execution of several British dignitaries, and they encounter an assassin who can produce fire from his bare hands.

When two fathers on opposite sides of the country are inexplicably murdered at the exact same time in the exact same way, Mulder and Scully are called in to investigate. When they discover that the two fathers' eight-year-old daughters are identical twins, they realize that something even stranger is going on.

Mulder puts the future of the X-Files in jeopardy when he heads to a UFO crash site being rapidly covered up by the military. He is arrested, and while in jail he meets Max Fenig, a UFO nut whose NICAP group has followed Mulder's work on the X-Files. When Mulder is released, Scully urges him to return to Washington to face his superiors and try to save his job, but Mulder finds out that Max is more than meets the eye and ignores Scully to try and save him instead.
