A new season of the show returns to Larvik on a seemingly idyllic summer evening at the Greenwood family. However, the following morning, a hotel employee is found murdered, and a six-year-old British boy named Clifford Greenwood has gone missing without a trace.
The family receives a ransom demand and cryptic messages from the kidnapper, and when family secrets are revealed, Wisting suspects that there may be a personal motive behind the disappearance. There is also enormous international pressure on Wisting and the team to solve the murder and find the boy before it is too late.
