Haunted by a personal tragedy, home care worker, Shoo (Clare Monnelly), is sent to a remote village to care for an agoraphobic woman who fears the neighbors as much as she fears the Na Sídhe - sinister entities who she believes abducted her decades before. As the two develop a strangely deep connection, Shoo is consumed by the old woman's paranoia, rituals, and superstitions, eventually confronting the horrors from her own past.
