In a town in northeastern Pennsylvania, Keller and Grace Dover, Franklin and Nancy Birch, and their respective offspring - each couple with a teenager and adolescent apiece - are best friends. While the two families are celebrating Thanksgiving together, the two adolescent girls, Anna Dover and Joy Birch, go missing. Based on events earlier in the day, the two families believe that the girls were abducted by whoever lives in the camper van parked in their neighborhood. Their beliefs are strengthened after they meet the resident of the camper, Alex Jones, a mentally childlike young man who is supported in every respect by his overprotective aunt, Holly Jones, and based on other subsequent evidence about Alex that emerges. However, Detective Loki, the lead police investigator, is pretty certain that Alex did not abduct the girls, he instead initially following leads of known sex offenders and pedophiles in the area. In addition, Loki has no evidence to hold Alex in custody, placing him at odds especially with Keller, who is certain that Alex is the one who abducted the girls. While Loki continues his investigation with Keller accusing him of not doing his job by following what he considers are pointless leads, Keller decides he has to take matters into his own hands. He has to decide how much he will involve Grace, Franklin and Nancy in getting Alex to divulge where the girls are by any means possible. His decisions as in who he will involve in getting Alex to talk may depend on how like-minded he believes the other three are, they who may be as devastated as he is, but who may neither be certain that Alex is the perpetrator or go to the same extremes as he to get the information from Alex.—Huggo

Now, the odds are against them, and Keller will have to take matters into his own hands, even if his reckless decision threatens to put his freedom at risk. Will he ever see the girls again, alive and in one piece?—Nick Riganas
Keller Dover (Hugh Jackman), a deeply religious man who runs a struggling carpentry business, attends a Thanksgiving dinner with his family at the house of their neighbors, the Birches. After dinner, the families' young daughters, Anna Dover, and Joy Birch, go missing. After a police hunt, an RV that had been parked in the neighborhood is found outside a gas station next to a wooded area. When Detective Loki (Jake Gyllenhaal) confronts Alex Jones (Paul Dano), the RV's driver, Jones tries to speed away, but collides with a tree and is arrested.
Loki begins questioning sex-offenders in the area. His investigation uncovers a corpse tied to a chair in the basement of a local priest. The priest claims that he killed the man when he confessed to having killed a number of children. The priest describes the man as "waging a war against God". Loki takes note of a maze pendant worn around the neck of the corpse.
During Detective Loki's interrogation, Jones is determined to be developmentally disabled, having the I.Q. of a ten-year-old. Despite many hours of aggressive questioning by Loki, he says nothing to indicate he had any connection to the missing girls. A forensics team that goes over his RV also find nothing to connect him with the crime. Jones is released due to lack of evidence.
When Dover confronts Jones outside the police station, Jones says to Dover, "They didn't cry until I left them," although no one else present hears this. Dover spies on Jones and hears him singing one of his daughter's favorite songs, which convinces him that Jones knows where the girls are. Dover abducts and imprisons him in an abandoned apartment building left to him by his late father. With the reluctant help of Joy's father, Franklin (Terrence Howard), Dover tortures Jones for days, but they obtain no further information. Overcome with guilt, Franklin tells his wife Nancy (Viola Davis) what they have done and brings her to see Jones. Franklin wants to release Jones, but Nancy demands they let Dover continue the torture, neither helping nor interfering.
During a candlelight vigil for the girls organized by neighbors, Loki sees a hooded man acting suspiciously. When Loki approaches him for questioning, he runs. The suspect evades Loki, but Loki manages to create a composite sketch of the suspect that is released to the public. Later, Anna's mother Grace (Maria Bello) hears shuffling coming from Anna's bedroom and after searching the room discovers her own bedroom window has been opened. She reports the break-in, which is investigated by Loki. Loki notices that Grace is under the influence of prescription drugs and does not take the incident seriously, but he searches the house with Grace. Grace leads Loki to Dover's basement, which is filled with survival supplies. Loki notices a half-empty bag of lye, and Grace reports that Dover has told her he has been out late each night helping the police search for Anna. Loki and Grace both know it's not true.
When Jones is reported missing, Loki becomes suspicious of Dover and begins tailing him. Loki discovers that Dover inherited the apartment complex when he finds the obituary for Dover's father, a corrections officer who committed suicide years before. Loki confronts Dover at the apartment complex, and Dover is able to conceal Jones's presence until Loki has to rush off in response to a phone call.
Based on tips from a children's clothing department clerk at a local store, and finally a car number plate report, Loki identifies the hooded suspect as Bob Taylor (David Dastmalchian) and confronts him at his home and arrests him. Loki finds that the walls are covered in drawings of intricate mazes. In a back room, he discovers locked crates filled with maze books, snakes, and bloody children's clothing. The Birches and Dover positively identify bloodied items of clothing found in Taylor's home. At the station, Taylor confesses to the abduction, though he provides no information about where the girls or their bodies can be found. While being questioned by Loki, Taylor grabs a gun from one of the officers that run into the room and commits suicide.
Despite Taylor's confession and the clothing found in his house, Dover continues to believe Jones knows where the girls are and continues torturing him. Jones finally speaks, mentioning escaping from a maze. Dover visits Jones's aunt, Holly Jones (Melissa Leo), to gauge her reaction when he mentions mazes. Holly says that Jones does not speak much, being very careful of what he says ever since an accident involving snakes when he was young.
It is determined that the blood found on the children's clothes is pig's blood. Only child-size mannequins are found buried in Taylor's yard, and no actual bodies. A forensic profiling person determines that Taylor had been abducted as a child and had been play-acting recreations of abductions based on descriptions in a true-crime book about a serial child abductor known as "The Invisible Man", whose crimes involve a book of unsolvable mazes. Loki determines the clothing identified by Dover had been stolen after the abduction, during the break-in reported by Grace, concluding that Taylor had faked his involvement in the abduction.
Days later, a drugged Joy Birch is found and hospitalized, but Anna is still missing. When Dover visits her in the hospital to ask for information, Joy, still disoriented from the drugs her captor gave her, says to Dover, "You were there." Dover rushes off, believing he now knows where Anna is. Loki tries to stop him but loses him. Loki goes to Dover's apartment building, where he discovers the imprisoned Jones.
Dover has realized that Joy must have heard him at the Jones's house. He returns to Holly's, prepared to torture her, but Holly takes Dover by surprise at gunpoint. She reveals that Jones gave the girls a ride in his RV, but had no thought of harming them, and that she alone was responsible for the abduction. She and her husband, the man whose body was found in the priest's basement, had abducted many other children, including Bob Taylor, in order to make their parents lose faith. She claims to be waging "a war on God" for letting their son die of cancer. Jones was the first child they abducted, at age 7 (26 years ago). Holly shoots Dover in the leg and imprisons him outside in a pit hidden under an old car, where he finds a whistle that belonged to his daughter. As Dover knows that he is losing blood and about to die, he prays for God to watch over Anna.
Loki goes to Holly's house to tell her that Jones has been found. He becomes suspicious when he hears someone moving around inside, but there is no answer at the door, and enters the house. He discovers a photograph of Holly's husband, wearing the maze pendant found on the body in the priest's basement. Realizing the danger, he is in, he draws his weapon and searches the house, discovering Anna being injected with poison by Holly. Loki orders Holly, at gunpoint, to show her hands; Holly turns and fires at Loki with her revolver, grazing Loki's forehead, as he shoots and kills Holly. Loki rushes Anna to the hospital where she soon recovers, and his wound is treated.
At the hospital, Grace thanks Loki, but also asks whether Dover, who is still missing, will go to jail if he is ever found, to which Loki responds, "Probably." At the Jones residence, a police team who have been digging in the yard pack up for the night, telling Loki as they leave that the frozen state of the ground means it will take weeks to dig up the entire place. As Loki prepares to leave, he hears the faint sound of a whistle. At first, he dismisses it, but then hears it more distinctly. As he turns to investigate, the screen fades to black.
