The Nevilles are the perfect family - Dad runs a floor cleaning business and Mum takes care of the girls, Sarah and Carlie.

It might seem that the only tension comes from Carlie sneaking out at night to see Jesse, the boy who lives and works at a nearby petrol station.

But something is wrong with this seemingly perfect family and, no matter how careful Sarah and Carlie are, they never know what might set their mother off.

They never know if they'll get dinner, or be able to take a bath, or talk to a new friend on the phone. And they are not sure if their hard-working dad even knows what is going on.

The only question is how long they can last like this before someone snaps.
