The Investigation

A home-built submarine, with a female Swedish journalist and the submarine builder on board, disappears.

Jens is pressured by the press; the journalist's parents help the police in their work; the case suddenly takes a violent turn.

The divers from the Navy search the seabed; Jens Møller gets a radical idea that can help the investigation.

Swedish dogs that can detect corpses that are more than 20 meters below sea level are brought in, but even though the dogs mark fairly accurately, the divers find nothing.

The case is coming together, but Jens Møller and his team still have no conclusive evidence; prosecutor Jakob Buch-Jepsen emphasises that they must have the motive and cause of death.

Prosecutor Jakob Buch-Jepsen makes it clear to Jens Møller that they need more solid evidence, otherwise they risk the accused going free.
