With "House of Ghosts," his first supernatural thriller, writer/director Christopher R. Mihm pays tribute to the works of the master of classic horror, William Castle! Rich socialites Isaac and Leigh have a tradition of throwing exclusive dinner parties that include unique (and expensive) forms of entertainment. This time, they've booked a spiritual medium who promises to "open a portal to the great beyond" and allow the couple's equally eccentric guests to contact the "afterworld." But, before he begins his presentation, the occultist offers a warning: once the door has been opened, no human being can anticipate or control what might come through. Regardless, the group collectively agrees to go forward, only to find itself greatly disappointed by the results... at first. Trapped in the couple's oversized house by a massive winter storm, the partygoers begin to experience unexplainable and increasingly frightening things. As these occurrences intensify, it becomes apparent that something evil is at work. Can the group survive the night or will ignoring the medium's warning be the last thing they ever do?
