Insomnia

This twisty crime drama is set in Alaska, during a time when the sun is permanently in the sky. Two Los Angeles police detectives arrive to help the locals with the brutal murder of a schoolgirl. They are also avoiding an Internal Affairs investigation back home. They have a suspect, and set a trap. However, in the mist, things go wrong, and one cop accidently shoots the other. This would not have been such a problem if the shot cop had not been planning on assisting Internal Affairs. The surviving cop covers up his crime, blaming it on their suspect. However, the suspect knows what actually happened, and suggests to the cop that they instead frame the dead girl's boyfriend for her murder. Things are further complicated by the local policewoman who is assisting with the investigation...
