On her last day as a Detective, Midge McGowan is given the retirement present from hell: a ticket to take part in a haunted house tour. She'll have to spend a weekend ghost-hunting in an isolated mansion, with a group of misfits, including a know-it-all paranormal investigator and a has-been pop star. It isn't long before the tour starts to spiral out of control. Midge and the guests see an unsettling figure walking the grounds late at night. Then the unthinkable happens - someone is murdered in a room that's been locked from the inside. Heavy snow cuts them off from help, the house's own dark secrets begin to surface, and Midge can't shake the creeping sense that they are walking into a nightmare. Could a ghost really be responsible, or is the culprit one of the guests?
