What would you do, if your mother felt like new, didn't act the way she should, behaved like mother never would, like a stranger in the house, makes you feel like a small mouse, quite aggressive and quite cold, not like the one you knew of old.
Elias and Lucas struggle to come to terms with their mother when she re-joins them after a period of hospitalisation. Taking matters into their own hands they explore a variety of ways to unmask their doppelganger and expose the truth.
