Three sisters are called to New York to hear the reading of their mysterious late father's will. The lawyer informs them of an eccentric stipulation: The sisters and their husbands must all spend three days together in the family mansion "in sexual harmony" before any of the considerable fortune can be divided. It is revealed that their father and mother never loved each other, and it is the deceased's wish that the house know connubial bliss for the duration of his daughters' stay. Though the youngest sister experiences strange premonitions of doom, the rest of the group are eager to reminisce together and strengthen their familial bonds. The servants the girls knew as children are still the caretakers of the old house, two spinster sisters and their brain-damaged brother. The trouble starts the very first night, when a gutted rabbit is found beneath a bed sheet, and a giant X is painted on a bedroom door in blood. The next morning one husband is found hanging from the staircase, and since the mansion is on an isolated island without electricity or phone, the rest have no choice but to stick it out for the weekend. The silent killer continues the murder streak with pitchfork, hacksaw, and axe, until a shocking family secret reveals the culprit and the motive behind the slayings. Also known as Legacy of Blood, Legacy of Horror is a remake of director Andy Milligan's own 1968 film The Ghastly Ones.
