Insomnia
In the small fishing town of Nightmute, Alaska, 17-year-old Kay Connell (Crystal Lowe) is found murdered. LAPD detectives Will Dormer (Al Pacino) and Hap Eckhart (Martin Donovan) are sent to assist the local police with their investigation, at the request of police chief Nyback (Paul Dooley), an old colleague of Dormer's. Also, an intense Internal Affairs investigation in Los Angeles is about to put Dormer under the microscope. Eckhart reveals that Internal Affairs has offered him an immunity deal in exchange for his testimony regarding one of Dormer's past cases. Eckhart says that he has no choice but to accept the deal, to Dormer's frustration.
Dormer comes up with a plan to lure the murderer back to the scene of the crime. The attempt fails, however, and the suspect flees into the fog. The police give chase, and the suspect shoots one through the leg. Dormer spots a figure in the fog and fires with his backup weapon and without calling out. On his way to the fallen figure, Dormer picks up a .38 pistol the suspect has dropped. He then discovers that he has shot Eckhart. As he dies, Eckhart accuses Dormer of murdering him. Because of Eckhart's pending testimony against his partner, Dormer knows that Internal Affairs will never believe the shooting was an accident. He tells his colleagues Eckhart was shot by the suspect. He doesn't mention he has the .38 pistol. Ellie Burr (Hilary Swank), a young local detective, is put in charge of the investigation of Eckhart's shooting. Police find the bullet that sliced the first officer's leg, a .38 caliber. That night, Dormer walks to an alley and fires the .38 pistol into an animal carcass. He retrieves the bullet and cleans it, then visits the morgue. The staffer hands him the bagged bullet retrieved from Eckhart's body. She is unfamiliar with its type. He leaves and switches the bullet with one from the .38.
Over the next few days, Dormer is plagued by insomnia, brought on by his guilt over killing Eckhart and further exacerbated by the perpetual daylight. He then starts receiving anonymous phone calls from the suspect (Robin Williams), who claims to have witnessed Dormer kill his partner. After looking through her belongings, the police learn that Kay was a fan of a local crime writer named Walter Finch. Dormer looks up his address in nearby Umkumiut and breaks into his apartment. Finch soon comes home, realizes the police have arrived, and evades Dormer after a chase.
Dormer returns to Finch's apartment. While there, he plants the .38 to frame Finch. Finch later contacts him and arranges a meeting on a ferry. Finch wants help in shifting suspicion to Kay's abusive boyfriend Randy Stetz (Jonathan Jackson) and will stay silent about Dormer's role in the Eckhart shooting in return. Dormer gives advice on handling police questioning. After Finch leaves Dormer on the ferry, he shows the detective a tape recorder he used to record the conversation.
Finch calls Dormer and tells him that Kay's death was "an accident" — he beat her to death in a fit of rage after she rejected his advances. The next day, Finch gives false testimony at the police station. When Finch claims Randy had a gun, Dormer realizes Finch has discovered his plant, and has hidden it at Randy's home. He races to Randy's house to find the gun before other officers, but is unsuccessful, and Randy is arrested. Finch offers to give Burr letters indicating that Randy abused Kay, and asks her to come and collect evidence from his summer home the next day.
Burr finds a 9mm shell casing at the scene, which conflicts with the bullet type found in Eckhart's body. She reads old case files from investigations Dormer was involved in and learns he has carried a 9mm, suspecting he has been lying about who shot Eckhart. Dormer confides in the hotel owner, Rachel Clement (Maura Tierney) about the Internal Affairs investigation: he fabricated evidence to help convict a pedophile he was certain was guilty of murdering a child.
Dormer searches Finch’s apartment for an address for his lake house, and realizes Finch intends to kill Burr after finding Kay's letters in the apartment. As Burr and Finch move through his house, Finch knocks the young detective unconscious. Dormer reaches the cabin, but is too disoriented from lack of sleep to fight off Finch. Burr revives and saves Dormer, while Finch escapes. Burr reveals she knows Dormer shot Eckhart. He admits it, but says he is no longer certain if it was an accident. From his shed, Finch shoots at them with a shotgun, and Burr returns fire with Dormer's gun, allowing him to sneak around to Finch's location. After a scuffle, Finch finds Burr's gun and shoots Dormer, who shoots and kills Finch with his own shotgun. Burr rushes to the fatally wounded Dormer's aid and comforts him by affirming that Eckhart's shooting was accidental, then moves to throw away the shell casing to preserve Dormer's secret. Dormer stops Burr, however, telling her not to lose her way and tells her to let him sleep as he passes on.
