The Truth Will Out

Detective Peter Wendel is assembling a new cold-case group, but the only people who apply for the job are Jorma and Caijsa, two cops who hate each other. But then an attorney is found murdered, with a note on his body stating that a notorious serial killer he defended is a fraud. Peter has no choice but to hire his lackluster candidates, along with Barbro, who isnt even a police officer.

Peters investigation leaks to the media, causing chaos at police headquarters and the justice department, where Peters ex-wife, Ann-Marie, works. As Peter hides his connection to the murder weapon, all the evidence indicates that a missing pedophile, previously a suspect in one of the serial killers murders, killed the attorney.

Peter and Barbro keep looking for the killer in Stockholm, as Jorma and Caijsa search the pedophiles house. Peter becomes a suspect when it comes to light that the murder weapon belonged to him, and Ann-Marie realizes that the minister of justice, who was involved in the serial killers trials, is trying to influence the investigation.

Peter decides to try to speak to the minister of justice about the old murder cases. In Hallstavik, Jorma and Caijsa find the missing pedophile and end up exposing a dark family secret. Later, Peter and Barbro talk to a witness whose testimony takes the investigation in an unexpected direction.

The cold-case group have to release their suspect, and Jorma and Caijsas old conflicts finally come to the surface and explode. Peters disdain for the minister of justice causes grave consequences for the team. Meanwhile, their suspect seems to be planning a horrible crime.

Peter refuses to accept his suspension and continues to follow the suspect, secretly aided by Caijsa and Jorma. The investigation takes Barbro to the village of sterbymo, where there was a mysterious disappearance many years ago. As Ann-Marie seizes an opportunity to document the conspiracy at the justice department, the suspected killer decides to talk to Peter, face-to-face.

Peter and his team feverishly try to track down their suspect, now finding even more disturbing evidence that the killer is planning something terrible. At the justice department, Ann-Maire finally confronts the minister, causing major consequences for all involved.

As the whole world watches, Peter and the cold-case group lead Swedens biggest manhunt in decades. Barbro returns to sterbymo to look for answers relating to that disappearance, which they now realize was the killers first victim. It seems like all is lost, when suddenly the killer contacts Peter for one last game of cat and mouse.
