Every day, Mary wakes up before dawn to make breakfast from scratch. She tends the garden and feeds the animals. Every night, Mary makes sure she has dinner on the table for when her husband Cal gets home from work. She puts on his favourite lipstick and greets him with a smile. 'I've missed you.' It's not true and he knows it. But he likes to hear it all the same. Their cabin is hidden deep in the woods in the Scottish Highlands, and Mary doesn't remember the last time she saw another living soul. She tries not to think about her life before too much.

Events spiral out of control, and a chance encounter with the wrong people leaves them in a horrific and desperate situation.

The other four children say Ivy is dead.
