当神秘专线响起，负责接听的你，愿意付出多少代价完成任务？
该剧改编自马修·奎克的同名小说，第一季结尾，FBI基层探员彼得·苏德兰（加布里埃尔·巴索 Gabriel Basso 饰）因拯救总统而立下大功。本季中，他将正式成为暗夜行动的一分子，然而，加入这个绝密组织，也意味着投身危机四伏、尔虞我诈的世界。
The new season returns to Larvik on a seemingly idyllic summer evening at the Greenwood family. But the following morning, a hotel employee is found murdered, and a six-year-old British boy, Clifford Greenwood, has disappeared 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.
