It’s never good when you move into a new house by a canal, only to find out it was the site of a grizzly turn-of-the-century murder. And it gets worse still when you learn about your house’s dark history not from the real estate agent, but instead by stumbling upon the important information while going through grainy National Film Archive footage as part of your job as a film archivist. Add to this life complication the suspicion that your wife is having an affair, and maybe it’s not surprising when you start to lose it and tear into your house’s walls in search of the source of noises you can’t explain. This Irish ghost story directed by Ivan Kavanaugh and starring Rupert Evans (“Hellboy”) is haunting, disturbing, and genuinely scary.
