Engström devises a plan to lure the murderer back to the scene of the crime, but the stakeout is blown and the murder suspect flees into the fog. Events take a turn for the worse when the fugitive shoots one of the pursuing unarmed Norwegian police officers. Without telling his colleagues, however, Engström carries a gun from his days in the Swedish police, who routinely carry firearms. While shooting at what he believes to be the suspect, Engstrom accidentally kills Vik, who had mistakenly run right instead of left as ordered.
