"A triumph of eerie bleakness, chilling the bones and haunting the mind." — Channel 4 Film
Two years after her sister Annie's mysterious disappearance, the police call off their search, but Kath (Shirley Henderson) remains haunted by the lack of answers. Determined to track down her sister, Kath stumbles upon what she insists is a direct link to her — a gateway to the afterlife from where Kath believes she can retrieve her. Her claim prompts friends to doubt her sanity, in spite of Kath's conviction that her supernatural discovery is real.
