An investment banker (Paul Mercurio) travels to Louisiana to snag the account of an eccentric millionaire (Malcolm McDowell) but gets involved with his lusty wife, Mardi Gras, and (possibly) a satanic cult. The events in and around New Orleans change him forever and give a new slant on The American Dream.
Set in the 1970s, House of Evil tells the story of a young couple who move into an old mansion in the Connecticut countryside to start a family. They soon discover that their new life is destined to be fraught with disaster as they fight against a dark, terrifying force in order to survive.
