The episode’s monster of the week is a ravenous pleasure seeker that hails from the Amish country and can change between male and female forms. The cold open shows an average looking woman seducing a man at a night club by putting her hand on his face, then taking him back to his apartment, having sex with him, him dying, then her changing into a man and fleeing the scene. Spooky for sure, and Mulder and Scully are called in to investigate. Mulder has seen deaths like this before, and he’s determined they originated with a Amish-like group called The Kindred in Massachusetts. When they travel up to their village, they observe spooky gender-switching rituals, Scully herself nearly falls victim to their out of control pheromones, and all around evasive behavior.
