The Delesormes' Plantation was a plantation and manor house in Louisiana owned by the Delesormes family. Despite being located miles from any water, the house was crushed and soaked as if by a tidal wave in 1980. It was told of in local stories as the "drowned plantation".
The Eighth Doctor travelled back to 1980 to witness the destruction of the manor. He watched as a circle of naked people conducted an occult ceremony, forcing a young boy into the center. The house imploded after being struck by a wave of water which came up from nowhere. The Doctor stayed with the young boy in the rubble until the arrival of the emergency services.
