Distraught after the untimely death of his daughter, Abraham Reed sets about capturing her image in clockwork; building a young girl so unquestionably real that even he is unable to fathom her making. On winding her, Abraham realises he has created something somewhat more than a machine. Constance, as he names her, can think… Terrified of being discovered, Abraham gives Constance one rule; to remain hidden from the outside world at all times. But the young creation, full of child like curiosity and frustrated with her limited existence, quickly forms other plans.
