Summer 2007, Finland. While the Kurtti are spending their annual holidays in their cabins in the land of a thousand lakes, the family is struck by a tragedy: Tommi, 2 years old, is killed by a gunshot. Elias, a 12-year-old neighbour, is blamed for the death of the child. 12 years later, the family receives a threatening anonymous letter and the secrets start to unravel, and show how far each of them are willing to go for their loved ones.
