An old monastery in a small, remote village has been haunted by a local legend for centuries. Left in ruin and shrouded by the mystery of a dark spirit that wills young couples to suicide, the property has been avoided for years, marked only by a decrepit old tree with an ominous hollow said to be the home of great evil. When four vacationing friends explore the local folklore, they realize that belief in a myth can quickly materialise into reality, bringing horror to life for the town.
