Intrigue

A police Lieutenant, his police force, and a vigilante become caught up in a dangerous scheme.

When the body of a young woman is found on a lumber truck, Detective Walter Marshall (Henry Cavill) suspects that the victim leaped to her death to escape from a captor. It was a freezing night, and the woman was barely dressed and had run through an ice field, before reaching the highway where she encountered the killer. To escape the killer, the woman leaped off the highway bridge and fell onto a lumber truck that was passing underneath.

Marshall believes that the woman landed on the truck from a height of 50 feet and died from the cold rather than her injuries. She has cartilage damage on her wrists, her ear drums were blown out, and she was given vitamin supplements and birth control pills.

Using CCTV cameras across the highway, Marshall finds the bridge from which the girl jumped on to the lumber truck. Marshall's team includes Matthew Quinn, Glasow, Profiler Rachel, his partner Dickerman (Daniela Lavender) and their boss Commissioner Harper (Stanley Tucci). It is revealed that many women have been reported missing in the past few years in the same area.

Marshall has a failed marriage with Angie (Minka Kelly) and share custody of their daughter Faye (Emma Tremblay). Faye is a rebellious teenager who is annoyed when Angie accesses her social media feed without her knowledge. Marshall tells Faye to profile the boys who send her friend requests. Marshall gives a list of Faye's male pursuers to Rachel to help him profile them by analyzing their social media feeds.

A breakthrough is inadvertently made in the case when former judge Michael Cooper's (Ben Kingsley) vigilante sting to capture a child predator result in his ward Lara (Eliana Jones) being kidnapped. Michael uses Lara as a sex bait to lure sexual offenders and then "sterilizes" them by removing their balls surgically and making them impotent. Michael had gifted Lara a set of earrings which have a hidden tracker inside them, which is activated whenever it is near a cell phone. So long as the earrings are near a cell phone, they can be tracked.

Michael is arrested by the police for rash driving when Lara is abducted, as he was following the tracker. Michael is forced to reveal his tracker to Marshall, who believes Michael and commits Police forces to track down Lara, leading to the discovery.

Michael's own family was killed by a sexual predator that he acquitted, who struck again. Thus, he started partnering with Lara (a sexual assault survivor herself) to serve vigilante justice. Now the signal from the tracker was lost at a cross-over bridge on the highway. Marshall reaches there and his team releases drones to look for further clues. The drones had a cell signal fitted to it, which activated the tracker when they got close to it. Marshall follows the signal and reaches a mansion in the middle of the woods.

Marshall finds Lara and other captive young women in a mansion owned by Simon Stulls (Brendan Fletcher), a seemingly-mentally disabled man. Simon is arrested and the police attempt to determine if he is responsible for the abductions. In investigating Simon's background, they discover that he was born from sexual assault and his mother attempted suicide before giving birth to him.

Rachael (Alexandra Daddario) is the police profiling officer who spends time in understanding Simon. Simon had equipment to make his victims deaf. This was a pressurized air valve which only burst the ear drum and left the cranium intact. Lara and Michael are not thankful to Marshall as Lara says that Police only shows up after the sexual assault has already happened.

During interrogating Simon does appear to be mentally unstable. He recoils at the sight of the pressurized air valve and clutches at his ear as if he himself had been hurt by it. Rachel realizes that Simon is deaf and gets him fitted with a hearing device. Rachael tries all sorts of shrink techniques and figures that Simon was severely abused by his mother, and was kept in a cage like a monkey, before she committed suicide. While Simon is in custody, the police force finds themselves apparently being targeted by another attacker (which leads to the death of 6 cops investigating Simon's house). Technician Matthew Quinn (Nathan Fillion) is killed in a car bombing and fellow technician Glasow (Mpho Kohao) is forced to free Simon when the life of his infant daughter is threatened.

Glasow had earlier helped Marshall hack Simon's secure drive and figure out that he was chatting with someone called Hacker71, who had access to military grade explosives and fuses. The police use this information to narrow down on a suspect. The ex-military man shoots himself when Marshall tells him that the equipment he sold was used to kidnap and sexually assault over 10 women.

The police recapture Simon after he has killed his father. Rachael and Marshall figure out that maybe Simon's father was the owner of textile factory where his mom was sexually assaulted. They figure out his address and reach the location to find Simon there and his father dead, This is when Michael discovers that Lara is missing. Believing Simon to be responsible, Michael ambushes his police transport when he is surprised by another man who looks exactly like Simon. It is then revealed that Simon is in fact a pair of identical twins, with one being behind the kidnappings and the other truly being mentally disabled. The twins kill Michael and capture police profiling officer Rachel Chase (Alexandra Daddario) before escaping.

Using a tracker that Simon left in the police station, a team led by Marshall locates the twins by an icy lake where they are holding Rachel and Lara. Lara escapes and Marshall takes the mentally disabled brother hostage to convince the malevolent brother to release Rachel. After Rachel is freed, Marshall tells the mentally disabled twin to hug his brother. The mentally disabled twin complies, causing both brothers to fall through the ice and drown.

Afterwards, Lara reads a letter from Michael thanking her for all that she has done. Marshall visits his daughter Faye (Emma Tremblay) accompanied by Rachel, implying that Marshall and Rachel have entered into a relationship.
