In the first episode, we travel far up into the mountains of Lapland, to take a trip down memory lane. Over 600 workers were staying in barracks around a power plant. What at first seemed like a normal day on the job soon turns into a crime scene like no other. The office safe has been robbed of all paychecks, and every single worker is a potential suspect.

When the police arrive at the scene of the crime, they’re left speechless. The levels of skill and planning involved are remarkable, and by reading documents previously never seen by anyone outside of the police force, Jenny Rogneby takes us one step closer to figuring out what happened on that fateful night in 1971.

The case was open for 10 years. From the beginning, the most pressing question was whether or not it was an inside job. The police reached out to the public and were flooded with leads; some helpful, some not. In this final episode of the series, a phone call to the person ‘everyone knows committed the crime’ is the last chance to get answers.

The case was open for 10 years and in total the investigation spanned to over 6000 pages. Lead after lead, after lead that never led to a clear conclusion. There were two options, either it was a inside job - or someone from the outside. Against all logic, the police put down a lot of resources to track down an outsider. But how could they miss the most obvious, logical route? And why has nobody ever been caught?
