They soon uncover the real reason Black Lake was abandoned all those years before, and solving the mystery rapidly becomes a matter of life and death.

Hanne, feeling increasingly uncomfortable in the isolated ski resort, tries to find out more about the tragic events that took place there 20 years ago and meets the retired detective who investigated the case.
