In the country-side cottage, in which they were born, two siblings discuss of their deceased father's diary; in which are portrayed witchcraft and black magic rites. Lucia claims that's all based on their father's aptitude for writing, while her brother, to support his claim, tells her about something he witnessed in his adolescence: an unexpected encounter, in the cottage's basement that revealed him a horrible secret. Is it a fragment of their imagination or is something actually hidden down there?
