When Head of Homicide for Copenhagen Police Jens Møller (Søren Malling) comes in for the morning briefing, an investigator reports on a strange case. A homemade submarine carrying a female Swedish journalist and the submarine's inventor has gone missing. When the submarine is located later in the day, only the submarine's inventor is rescued before the submarine suddenly sinks. Now Jens Møller and his team of investigators must quickly decide how to approach the case, as the journalist is still missing and the submarine is at the bottom of the sea.
