The girls go look for Maryberry, who has disappeared. Meanwhile, some of the girls may have figured out the cause of the supernatural phenomena they've been sent to investigate.
♬ I know that someone's Knocking on my door ♬
Knock – Ich weiß,
dass es gleich klopfen wird.
Sé que alguien toca a mi puerta
Même si on frappe à ma porte
Eu sei que alguém está
Batendo na minha porta
