Jaidee seems to have died twice, both on Ofärdsön and in the tsunami disaster. Bäckström wants to interrogate the widower Daniel, but when Hwass gets in the way and his colleagues distrust him, Bäckström proceeds with the investigation on his own.

Bäckström is convinced that Jaidee faked her own death in connection with the tsunami, but the group is skeptical and Bäckström lacks evidence for his theory.

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

Bäckström is struggling after a big betrayal, but refuses to give up. Important questions still need answers. Who killed Jaidee and why? And is it still possible to die twice, if one can now live twice?

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

The murder of Eriksson seems to be difficult to solve, not least when Bäckström is removed from the investigation, and Ankan takes over. Bäckström begins to dig into the beating of Baron Von Comers, suspecting that the two cases are connected.

Ankan begins to question Bäckström's honesty. Eriksson turns out to have been carrying a big secret and now light has just been shed on the night of the murder. Olsson risks ruining the entire investigation in a desperate attempt to impress Ankan.

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 Bäckström's best friend in the hope of leading the investigation forward.

Bäckström realizes that he has to hand over Pinocchio to the Russians, the problem is that he doesn't know where the music box is. Ankan finally sees through Bäckström's lies, and the relationship between them is put to the test. Can they still manage to solve the case?
