The film begins in 1983 at a dreary Anchorage motel room, where 17-year-old Cindy Paulson is found handcuffed and desperately screaming for assistance. She is swiftly saved by a patrol officer from the Anchorage Police Department, who promptly transports her to the hospital, with her clothing being preserved for a rape kit examination. At the precinct, Cindy recounts her traumatic ordeal to detectives, revealing that she was abducted and subjected to repeated sexual assault. However, due to her status as a prostitute and her deceptive age claims, the detectives dismiss her allegations. They portray her abductor, Robert Hansen, as a model citizen—a family man, restaurant owner, with a solid alibi supported by three individuals.
The officer who rescued Paulson is incensed by the detectives' inaction. Acting on his instincts, he secretly makes copies of the case details and forwards them to the Alaska State Police. Concurrently, state trooper Jack Halcombe is assigned to investigate a gruesome discovery: a female body found in the wilderness, partially devoured by bears. Investigating further, police uncover a disturbing link among other missing girls, most of whom went missing after attending what they believed were legitimate photo shoots. Armed with sensitive intel from the APD officer, Halcombe begins to connect the dots between the cases and Paulson's story, piecing together a disturbing profile of Hansen.
Cindy shares harrowing details of her captivity, including her narrow escape from Hansen's vehicle during an attempted transfer to his bush plane. Meanwhile, another woman, Debbie Peters, is deceived by Hansen, who picks her up under the pretense of a photo shoot. Later, Hansen invites Debbie to dinner at his home while his family is away, all the while ignoring her cries for help as she finds herself bound. In a chilling moment, Hansen vacates the trophy room where Debbie is held captive, only to return later and force her into a deadly game that sees her fleeing into the wilderness, where Hansen callously hunts her down.
As Halcombe struggles to build a case against Hansen due to the circumstantial nature of the evidence and Paulson's reluctance to testify, she attempts to re-enter her previous lifestyle, only to spot Hansen prowling for another victim at a strip club. Their paths cross, leading to a tense chase that barely results in her escape. This encounter leads Hansen to hire Carl Galenski, offering to clear a debt in exchange for the capture of Paulson.
Halcombe intensifies his surveillance on Hansen, but the predator grows wary. Prompted by escalating fear, Hansen attempts to eliminate evidence linking him to his crimes, including the trophies taken from his victims, as he escapes with his son to the airport. With 17 confirmed victims on his conscience, Halcombe pressures the district attorney to authorize a search warrant. However, an initial search yields no incriminating evidence, leaving Halcombe frustrated.
Despite being questioned, Hansen maintains his cool, revealing nothing to police. Another search of Hansen's residence ultimately uncovers a hidden collection of firearms, including the .223 caliber rifle linked to numerous murders. While under police protection, Cindy slips away and returns to her previous life, leading to a dangerous encounter that almost costs her, but Halcombe arrives just in time to save her.
In a clever ruse, Halcombe uses a bracelet identical to one belonging to a victim to provoke Hansen into a confession, using Paulson's presence in the interrogation room as leverage. The film closes with a somber epilogue, highlighting Hansen’s admission to murdering 17 women and assaulting 30 others, with him receiving a staggering 461 years plus life without the possibility of parole. Robert Hansen passed away in 2014 at 75, with only 11 of his victims' remains found. Halcombe continued his service with the Alaska State Trooper, eventually retiring, while Cindy Paulson now leads a peaceful life in the lower 48, happily married with three children.
The film poignantly concludes with a dedication and actual photographs of Hansen's victims, reminding viewers of the chilling reality behind the fictional narrative.
