Sepulcher of the Damned

After winning the lottery, a former systems administrator retires to rural Indiana to build a new house. His dream property isn't empty, however, as an old and decrepit mansion still sits near the lake. Deciding to stay there as his house is being built, Mike begins to have strange visions of the past occupants. He enlists the help of his workmate, Leonard, who is recently estranged from his wife, and the two begin trying to unravel the mysteries that lie in the mansion itself, a wooded island on the lake, and a deceased cult leader whose demonic legacy is as dark and disturbing as it comes.
