The story begins when Samuel is found dead in the snow outside the isolated chalet where he lived with his wife Sandra, a German writer, and their partially-sighted 11-year-old son Daniel.

Daniel is caught in the middle: between the trial and their home life, doubts take their toll on the mother-son relationship..
