A woman is found murdered in the middle of Oresund Bridge, exactly on the border between Sweden and Denmark. Saga Noren from Malmo CID and Martin Rohde from the Copenhagen police department are called to the scene.

It now dawns on the police that the final step in the murderer's evil plan has a new direction. Saga does all she can to crack the case and catch the killer - will she succeed before it's too late?

The murderer makes his presence known and chooses sharp-witted tabloid journalist Daniel Ferbe to act as middle man to communicate with the outside world.

In Copenhagen, several homeless people have been poisoned. The perpetrator wants to draw attention to the problem of the increased number of people falling through the cracks of society.

The homeless man's survival becomes a race against time and depends completely on the four landlords' willingness to pay what the murderer demands.

The murderer has groomed a number of schizophrenic people over a long period of time, convincing them to commit carefully synchronised violent crimes in Malmo and Copenhagen on the same day.

Copenhagen is up in arms following a court case in which a group of police officers who beat an immigrant to death are found innocent.

The murderer's fifth and final truth is the public's indifference to child labour, with millions of children being exploited daily in order to produce goods as cheaply as possible.

After many suspicions and one witness statement, Saga and Martin arrest and question a fellow officer. He turns out to have an alibi for all the crimes, but is he really innocent?

Gradually all the pieces to the complicated puzzle are put in place. The clues and evidence in the investigation have led the police to a man who could be the murderer.
