In Pennsylvania, Keller Dover, his wife Grace, son Ralph, and daughter Anna celebrate Thanksgiving with their friends Franklin and Nancy Birch, and their daughters Eliza and Joy. The four children go for a walk, and Anna and Joy play on a parked RV. After dinner, the two go missing. Detective Loki responds to a police call that an RV matching the description is at the edge of the woods, and arrests the man inside, Alex Jones. Prisoners 2013 full Movie
During interrogation, Loki realizes Alex’s diminished IQ prevents him from planning a kidnapping and learns that his RV contains no forensic evidence of the missing girls. Loki runs down leads on local pedophiles and finds a corpse in the house of Father Patrick Dunn. Dunn admits to killing the man after he confessed to murdering 16 children for his “war on God”.
The police captain releases Alex to his aunt, Holly. Convinced of Alex’s guilt, Keller assaults him outside the police station, where Alex whispers to him, “they didn’t cry until I left them”. After Loki finds no proof of this, Keller kidnaps Alex. Along with a very reluctant Franklin, Keller begins to torture Alex in an empty building Keller owns.
At a vigil for the girls, Loki approaches a suspicious man who flees. Loki releases a sketch of him to the community. The suspect sneaks into the Birch and Keller houses. Grace hears him and calls Loki, who learns while responding that Keller spends his nights away from home. He tails Keller to the empty building, where Keller claims he goes to drink, but Loki doesn’t find Alex. Loki tracks down the suspect, Bob Taylor, at his house. The walls are covered in maze drawings and Loki opens crates filled with snakes and bloody children’s clothes.
At the police station, Taylor confesses, and Loki discovers he was abducted as a child. As Taylor draws detailed mazes, Loki assaults him and demands the location of the girls.
