Backstrom

The chief inspector leaves a robbery case to a colleague, because he's only interested in murder cases.

A murder victim seems to have died twice, both on a distant island and many years earlier in the 2004 tsunami, and Bäckström wants to interrogate the widower.

Bäckström travels to Thailand to dig for clues around Jaidee's life and death, and everything points to Jaidee having died in the tsunami.

Bäckström has a theory about what might have happened to Jaidee, but the team is skeptical and he can't prove anything yet.

Bäckström has been suspended but can't stop himself from lending a hand in the homicide investigation.

Bäckström is struggling with the feeling of having been betrayed by someone close to him, but keeps it to himself as he's put back on the job.
