The film sees a now-retired and married Palmu helping the Finnish Broadcasting company discover the truth behind the murder of one of their reporters.

An important agreement on a tunnel building project is being held between Finland and Soviet Union in secrecy, over fears of their political effects.

When the press catches wind that the meeting is held at the foreign minister's manor, the talks are hastily moved.

A reporter for the Finnish Broadcasting Company, is murdered on the grounds of the manor and his camera-man is caught by the guards.

Eventually, Palmu realises that the murder was politically motivated and that a far-right underground group was looking to silence the reporter and sabotage the talks between Finland and the Soviet Union.
