Buried

Home is where the heart is ... or the hatred.
You can feel the love and care someone puts into their home just by walking into it. Equally, you can feel the hatred and malice when you step into a home where dark deeds have been done.

Alex and his team of so-called paranormal investigators are given the opportunity of a lifetime when they are able to film inside one of the most haunted, and cursed, locations in their area.
The Jackson Mansion.
The thing that makes this mansion truly unique is that it is built completely underground. Determined to uncover the dark secrets of the mansion's past, and prove himself a notable investigator, Alex doesn't care what it takes. The mansion, however, has other ideas, as well as some rather restless occupants.
