Scully and Mulder travel to a small town when there are reports that five babies were recently born with vestigial tails. Four of the five women were artificially inseminated at the same clinic but the fifth claims to have had sex with Luke Skywalker. Scully thinks it's all nonsense but their focus soon falls on Eddie Van Blundht, a janitor at the fertility clinic. His father had been a circus performer but Eddie seems to have another power: to take the appearance of anyone around him. Things get interesting when he decides to pretend he's Mulder.
