A journalist is murdered in the underground car park at the headquarters of Norway's biggest newspaper. Was the killing part of an organised campaign to permanently silence particular correspondents?
Surveillance tapes of Thorgrim Hammern's murder are leaked. Peter Veras and Frank Mathiesen suspect that he had stumbled onto something big. Hoping to pick up some leads, they visit his wife Ellen.
Technology journalist Georg helps Peter to locate a log of conversations between Hammern and someone calling himself 'No Reason'. Peter decides to meet this person, but it turns out to be risky.
It seems the shooting of another victim and Mathiesen's dangerous meeting with the killer are somehow linked to the prime minister's education reform. Peter and Ellen try to dig up Hammern's secrets.
Tension grows as Ellen, Peter and Mathiesen are held hostage by the person Hammern tried to squeeze for information. Cabinet ministers squabble over who should lead the hunt for the political killers.
Peter is sure that Ellen's in danger and discovers her house is under surveillance. The national security service has an internal problem of its own, with leaks influencing the cabinet power struggle.
Ellen and Peter go abroad searching for the photographic evidence that got Hammern killed. They try to hack into a database, but their attempt at obtaining the pictures they need goes horribly wrong.
A major trade deal is about to be settled and the country's future is at stake. Ellen and Peter are the only ones who can change the outcome, if they can escape from the clutches of their enemies...
