Rachael is a recovering alcoholic who checks out of rehab and goes to stay with her religious mother Sylvia. Sylvia blames Rachael for the disappearance of Rachael’s brother Matthew eight years ago, and Rachael’s daughter Joanna three years ago, both under mysterious circumstances in and around some ominous old tunnels in the neighborhood. As Rachael sifts through the wreckage of her life she finds a mysterious jar under her old bed labeled ‘Mr Davies’; a link to a past she can’t remember. She becomes drawn to the tunnels as she learns about other mysterious ‘disappearances’ in the area, and it soon becomes apparent that her daughters disappearance was anything but that; and that she will have to face her past in order to get her back.
