After encountering a ghost in their vacation home, modern artist Dan Pappadakis and his wife Mary hire an exorcist – the bizarre and needy Os Bijourn. Implementing a variety of increasingly outlandish (and dubious) devices to battle the ghosts, Os tries to befriend Dan almost as relentlessly as he tries to fight the ghosts. However, things turn suddenly serious when Dan realizes that a great danger lurks within the home.
