Insomnia

In the small fishing town of Nightmute, Alaska, 17-year-old Kay Connell is found murdered. Los Angeles Police Department (LAPD) detectives Will Dormer and Hap Eckhart are sent to assist the local police with their investigation, at the request of police chief Nyback, an old colleague of Dormer's. Ellie Burr, a young local detective who is also a fan of Dormer's investigative work, picks them up when they arrive. Back in Los Angeles, Internal Affairs is investigating one of Dormer's past cases. Flying to Alaska, Eckhart reveals that he is going to testify against Dormer in exchange for immunity, to which Dormer responds that many criminals whom he helped to convict using questionable evidence could go free if their cases are reopened.
