1962. A lonely house in the English countryside. Rose, 16, plays a two-player board game alone. Each time she rolls the dice, we are pulled further into her murky, fragmented world. With a mother who cannot understand her, Rose's only solace is found in glimmering moments spent with her sister, playing games and telling secrets at the bottom of the garden. But as Rose attempts to flee the confines of reality, the shadow of the family doctor looms over the house.
