[5] Set during the late years of World War II in a fictional town in Tuscany within German-occupied Italy, twin sisters Martha and Giulia spend their childhood in their nanny's estate.

Giulia's nanny recounts the legend of the White Lady, a malicious spirit of a woman who was hung from a tree by her lover on an island in a nearby lake.

While exploring the surrounding woods, Giulia finds the corpse of her boyfriend, Lapo, a soldier of the Italian resistance, before she's shot.

Suspecting that her mother played a role in her sister's death, Giulia obtains instructions to contact the White Lady from her Nanny.

After using tarot cards to communicate with her on the island, Giulia obtains the key to her sister's trinket box and wakes up in her estate.

Giulia travels to her family's crypt and disembowels Martha's body to retrieve the deceased fetus.

Before developing the reel of film from the day Martha died, Giulia interrogates and shoots Irene, finding the key to her childhood bedroom.

In the present, Giulia calls the town's priest, who convinces her to come to the church, where staff from the mental asylum finally take her away.
