Three days into her stay, Cormac and Sorcha's son Tadhg becomes ill. That night, Victoria lies in her bed in the kitchen that she shares with the old servant Martha. Unable to sleep, she looks out the window and sees a white, almost green face staring in the window. She screams, which brings Cormac, Sorcha and Cormac's brother Niall running to the kitchen. Victoria tells them she saw a monster, but the face is gone. Now that the household is awake, they notice that Tadhg has a bad fever.
The next day, the doctor attends Tadhg. He plans to bleed him, but Victoria protests, saying that he needs to be kept warm. No one listens to her, and she makes her way to the kitchen, where Martha still lies in her bed. She is dead.
Later that day, Sorcha wants Victoria to pray over her rosary with her, but Victoria can't because she's a Protestant. That night, Victoria sees the face at the window again, and screams again. However, the family doesn't come to her because Tadhg has died.
Next morning, Sorcha is ill. Niall returns from visiting the village to report that seven people, including the doctor, have died from the fever. Victoria decides to look for the monster by daylight, but the villagers she encounters warn her away, saying, "Keep away! Diseased!"
Cormac becomes ill and is put to bed with Sorcha. Victoria tries to convince Niall that the monster is causing the illness, but he thinks it's a punishment from God.
Once again that night Victoria sees the face and screams. Niall enters but sees nothing. He rushes upstairs, and Victoria follows. Cormac and Sorcha are dead. Niall, enraged, calls Victoria a witch and begins to strangle her. He is stopped by the Doctor and Jamie, who have just arrived.
Victoria tells the Doctor everything, and he tells her the disease is the Black Death. He also notices that Niall is suffering from the plague.
That night, the Doctor and Jamie keep watch with Victoria. When the face appears, Victoria screams, but the Doctor calmly calls the monster in. He identifies it as a Banshee, whose cry heralds death. The Banshee has come for Victoria, not as a victim of the plague, but as someone whose scream has heralded several deaths. The Doctor refuses to let Victoria go with the Banshee, and explains that there is one person in this family who will not die — Niall. The Doctor has given Niall some of Victoria's blood, which has some protection against the plague. The Banshee shrieks and disappears.
Back in the TARDIS, Victoria thinks about all the deaths she has seen.
