A pregnant woman's baby is snatched away from her belly by a devil. Agent Spender believes the case is a joke, but Mulder decides to look into it on his own anyway. His investigation focuses on the woman's husband.
Mulder suspects demon fetal harvesting when a woman claims her unborn child had a horn and tail and was taken by a devil while she slept. While others conclude that the woman killed her own baby, Mulder suspects that her husband is involved and that he may be the devil in disguise.—Muldernscully
