Delve into the dark side of famous American folk tales, exposing the horror at the root of these enduring mysteries. In this two-hour special, we visit five Haunted Houses, including the Donnelly Farm in Lucan, Ontario, once the blood soaked site of a massacre. Here an Irish immigrant family was burned alive when fear and ignorance led to revenge. Descendants of vigilantes who killed them are still haunted by what they did. Also, 170 years ago, illicit love flourished in the house on Rue Royale, New Orleans. Inside, a rich white man and a poor black woman fought odds to be together. Misunderstanding led to death, and today the young mistress is said to still haunt this place, trying to recapture her forbidden love.
