The film begins with the description of an obscure occult practice in which people feed aborted fetuses blood to raise 'young ghosts'. These ghosts become powerful and bring fortune to families but at the same time can be commanded to bring death. We then see an entire family hanging in a room and a young woman crawling beneath their feet. She then proceeds to hang herself. After the grisly opening the film fast forward to present day. A young architect is inheriting the house, recently back from abroad. After some argument, he manages to convince his dancer fiance to live with him, and they celebrate one night in the house.
The next few days, strange things begin happening. Their friends start showing up at the house at midnight with no memory of how they got there. Footprints begin appearing on the floors, followed by strange noises. One of the friends is later found dead in their apartment, their neck bearing markings of being hung where no rope is present. The detective, suspicious of the couples late night visitors spends the night at their house hoping to catch them sneaking in. After being witness to the strange occurrences himself, he finds his himself showing up at the couples house late at night with no memory.
