Lucy enters the mansion, which is filled with stuffed animals, and finds Mrs. Wilson at the bed of the patient, Mrs. Deborah Jessel.

In a room filled with stuffed animals gathered around a tea table, they find a single locked door.

Lucy suggests that this is the corpse of Jessel's mute daughter Anna, still dressed in a ballerina outfit.

They hear noises from the floor above and try to flee the house, but the window through which they entered is now secured by iron bars.

There is a flashback demonstrating that Mrs. Jessel was a very strict ballet teacher: a girl leaves the ballet class and Jessel later finds her lying dead in Anna's room; Anna is bent over the girl, drinking her blood.

While Wilson watches, Mrs. Jessel implants the pupae of a moth into the throats of Lucy and Anna; this is a ritual to exchange their souls.

Lucy whips her mother until she releases Anna, and the two girls throw Jessel off a third floor balcony.
