Officer Domo and partner Eckhart travel to Alaska to investigate a teenage murder. Domo has rich experience in handling cases. When handling a case in Los Angeles, in order to arrest a criminal, Domo fabricated false evidence and completed the case. This matter was investigated by the Internal Affairs Bureau. Eckhart knew about it and thought it was not a big problem.
As soon as Domo arrived, he grasped the crux of the problem and used the girl's schoolbag to lure the murderer. A group of cops followed, and the murderer appeared in the river hut. Domo and Eckhart tracked them all the way. The fog was thick, and Domo shot and killed Eckhart, who believed Domo did it on purpose. Domo explained to the police that the killer did it, and then hid Eckhart's gun. Domo has suffered from severe insomnia since then.
After the autopsy, the bullets were taken out, and Domo unpacked the bullets to relieve himself of suspicion. According to the girl's clues, Domo found the girl's boyfriend, and then learned that the girl had a relationship with the writer Robert, and was looking for the writer. At this time, the writer called to make a deal with Domo and asked Domo to help him clear the suspicion. He admitted that he did it himself, but he saw Domo shoot and kill Eckhart. Domo and Robert reached a compromise. They put the blame on the murdered girl's boyfriend. For this reason, Domo secretly put the gun in the girl's boyfriend's house, and the boy was arrested. The evidence is conclusive.
The policewoman who worked with Domo found the writer. Domo arrived in time and died with the writer. The policewoman told the truth according to Domo's wishes.
