Valerie has been forgetting things. Her daughter worries about her being on her own in her big Victorian house, and truth be told, she is a little lonely. With few options, she asks her adult son to move home, but it's not quite the reunion she hoped for. Hudson is taciturn, moody, and frequently gone. When a young woman is found murdered a block away, suspicion falls on him immediately, without a shred of evidence. While Valerie fights to defend her son, she begins to wonder who she really invited into her home. It's a horrible thing for a mother to even think . . . but is it possible she's enabled a monster? A monster she is living with, alone?
