Physicist Lionel Barrett has been asked to make an investigation into the subject of "life after death" in the notorious Belasco House (owned by millionaire and accused killer Emeric Belasco). The house is believed to be haunted by Belacso and the people he has harmed throughout the years through his sick ways.

Barrett is joined by his wife; Ann Barrett; a young female psychic; Florence Tanner; and a survivor from a previous visit; Benjamin Franklin Fischer; to Belasco House (now known as Hell House). They must survive a whole week inside the evil house and find out the mysteries and horrors that exist inside to rid its vial spirits without becoming the next victims.
