Bäckström

Homicide investigator Evert Bäckström is convinced that a crime has been committed when a womans skull is found on an island in the archipelago. But his investigation is opposed by the chief of police; and when the womans identity is clarified, the whole investigation is turned upside down.

Bäckström goes to Thailand to dig for the truth about Jaidees life and death. At the same time, the investigation group in Stockholm follows a completely different track. They are convinced that Jaidee died in the tsunami and soon the Asian Mi Mis husband is arrested.

Bäckström is suspended, but still continues his private investigation with the help of Edvin. Together they go to the scout camp to confront Edvins scout leader Haqvin, who turns out to have connections to both Jaidee and the site where the skull was found.

Bäckström is the first to arrive after celebrity lawyer Tomas Eriksson is murdered. The police initially cannot rule out that Bäckström himself is involved.

An old Russian music box made of gold, representing the fairytale character Pinocchio, worth around 300 million kroner, seems to be the motive for the murders. Bäckström is trying to find the music boxs former owners.

Bäckström receives death threats and it seems that Tina is the only one who can help him. The police, led by Ankan and Olsson, target Bäckströms best friend in the hope of leading the investigation forward.

Bäckström travels to Palma, Mallorca, with Niemi to pursue a lead in the murder of his childhood friend Sally, his only unsolved case. Meanwhile, an explosion in central Stockholm may be linked to a drug cartel.

Bäckström attempts to convince Wall and Toivonen to stay in Palma and continue his investigation, but he has his hands full with two cases that are seemingly intertwined.

With new evidence pointing to an unexpected suspect, a large shipment of cocaine is about to arrive in Palma. Wall seeks Moraless help to intercept the shipment before it is smuggled in to Sweden.
