It’s been two years since we last saw Viggo Lust. He has cut all ties to the past and started working in organised crime. But when he witnesses a murder, he has to cooperate with his old colleagues.

After witnessing a murder in Oslo’s underworld, Viggo is forced to work with his former colleague Mari, whom he still hasn’t forgiven. Viggo sees Christina again, and she has a clear message: Mari is going to get shot.

Viggo and Mari get closer to a possible killer and get closer to each other as well. At the same time, Viggo and his ex-wife, Sofie, are getting back together.

The pictures of Viggo’s brain after the heavy nosebleed show that something might be very wrong. A suspect disappears right under their noses, and once again Viggo sees visions of Mari getting shot.

Viggo averts a murder attempt on Mari, and is happier than he’s been in a long time. His ex-wife is now his girlfriend again, and things are good. But to Viggo’s astonishment, Christina still shows up with warnings.

Viggo still has visions of the killer, and fears that they have the wrong guy in custody. Viggo breaks up with Sofie to spare her from losing yet another person she cares about after getting bad news from his doctor.

Viggo is still certain that Mari is in critical danger. There’s also no doubt that they have the wrong killer. There’s a “Mr X” out there, and Viggo has to find him before it's too late.

The hunt for the killer ramps up, and Viggo is the only one who doubts that they have the right guy. The more he searches, the more sure he is that they're wrong.

Viggo realises who the killer is, but no-one believes him. Instead, he’s going to be suspended because of his odd behaviour. Viggo still fears something is going to happen to Mari. When it does, can Viggo solve the case?
