Mulder and Scully are stalked by an ancient legion of lethal beings while investigating a boy’s claims that he was attacked by an invisible creature.

Nash tracks down a pension accountant who has embezzled $7.3 million in cityfunds; Bettina is fired after blowing up the suspect's house and returns to bountyhunting; and Caitlin throws Nash's Willie Mays autographed baseball through a window during an argument.

Dr. Mark Sloan (Dick Van Dyke) finds himself in the middle of another murder investigation that hits too close to home. Mark learns that his friend, Jake Caldwell (Patrick Neill Quinn), has not only been murdered, but has left behind two wives, a mistress, and a suspiciously loyal secretary, which leaves Mark and Lt. Steve Sloan (Barry Van Dyke) with four suspects and a difficult question to be answered, "Who did kill Jake Caldwell?"
