Boston is being terrorized by a series of seemingly random murders of women. Based on the true story, the film follows the investigators path through several leads before introducing the Strangler as a character. It is seen almost exclusively from the point of view of the investigators who have very few clues to build a case upon.

Detectives Jonas and Erik are called to the midnight sun country of northern Norway to investigate a recent homicide, but their plan to arrest the killer goes awry, and Jonas mistakenly shoots Erik. The suspect escapes, and a frightened Jonas pins Erik's death on the fugitive. Jonas continues to pursue the killer as he seeks to protect himself; however, his mounting guilt and the omnipresent sun plague him with an insomnia that affects his sanity.

James “Brick” Davis, a struggling attorney, owes his education to a mobster, but always has refused to get involved with the underworld. When a friend of his is gunned down by a notorious criminal, Brick decides to abandon the exercise of the law and join the Department of Justice to capture the murderer.
