Wealthy Richard Walker has just died, leaving behind his country house full of rooms packed with the detritus of a lifetime. His estranged family - bitter ex-wife Caroline, troubled teenage son Trenton, and unforgiving daughter Minna - have arrived for their inheritance.
But the Walkers are not alone. Prim Alice and the cynical Sandra, long dead former residents bound to the house, linger within its claustrophobic walls. Jostling for space, memory, and supremacy, they observe the family, trading barbs and reminiscences about their past lives. Though their voices cannot be heard, Alice and Sandra speak through the house itself - in the hiss of the radiator, a creak in the stairs, the dimming of a light bulb.
The living and dead are each haunted by painful truths that will soon surface with explosive force. When a new ghost appears, and Trenton begins to communicate with her, the spirit and human worlds collide - with cataclysmic results.
