From the moment Stewart Hanson married Terri, her grandmother Crystal has been a thorn in his side. Now, Crystal Colburn is coming to live with them. Beyond Crystal's obsession with belittling Stewart is her obsession with a disconnected vintage phone. She constantly talks on it, as if reliving conversations with long dead friends. As her "conversations" begin to focus on her disdain for Stewart, Stewart is drawn further into insanity in this Hitchcock-style, paranormal thriller.
