The
Investigation

We follow Head of Homicide Jens Møller and his team over the course of six months, as they investigate what the press has dubbed THE SUBMARINE CASE. On paper, it looks like a very simple case of murder: A man and a woman set out to sea in a submarine. The man sinks the submarine and returns to shore alone. When the submarine is recovered, the police find traces of blood from the young woman in the submarine, despite it having been flushed through with water.

However, the investigation quickly proves not to be quite so simple. There is no body, no murder motive and no murder weapon. And every time Jens Møller and his team make progress, the accused changes his explanation of what happened on board the submarine, so that again and again doubt is cast on the theories of the police and the validity of their proof is questioned.

THE INVESTIGATION hones in on Jens Møller’s methodical investigative work. On the Swedish cadaver dogs that are trained to find bodies submerged under water. On the sea currents at Øresund, the strait between Denmark and Sweden. On the victim’s family, her boyfriend, and the life she led before it was so brutally cut short.

THE INVESTIGATION shows us what happened behind the scenes in the most discussed and publicized murder case in Danish history, and why exactly this case became one of Jens Møller’s last as Head of Homicide.
