In a village located in the central French region of Sologne, a young girl notes the negative effects of urbanization on her environment; then she imagines the appearance of the Ampélopède, a strange creature living in the woods.

A detective narrates this story of police investigating three murders and discovering that their leads take them to the heart of a white slavery ring that is also in the drug trade. Men set up parties, invite young women, and then drug them, kidnap them, and sell them off to brothels.
