What dark clouds hide

On a summer's day, Johanne Vik arrives at the home of her friends Jon and Ellen Mohr and is greeted by a scene of devastation: their young son, left unattended, has tragically fallen to his death. Meanwhile, Oslo is under attack. An explosion has torn the city apart and the eyes of the police department are focused elsewhere. A newly qualified officer named Henrik Holme is the only one available to attend the Mohr household. As Holme begins to investigate, he calls upon Johanne for assistance, and casts doubt on the claim that the death was a tragic accident. But there are shadowy figures at work, as yet unseen by Johanne or Holme, determined to hide the truth. Meanwhile, Johanne's husband Adam Stubo - preoccupied with his police work - doesn't see the danger his wife is placing herself in: will the pieces of the puzzle fall into place before it's too late?
