When Keller Dover's daughter and her friend go missing, he takes matters into his own hands as the police pursue multiple leads and the pressure mounts.

How far would you go to protect your family? Keller Dover (Hugh Jackman) is facing every parent's worst nightmare. His six-year-old daughter, Anna, is missing, together with her young friend, Joy, and as minutes turn to hours, panic sets in.

The best lead is a dilapidated RV that had earlier been parked on their street. Heading the investigation, Detective Loki (Jake Gyllenhaal) arrests its driver, Alex Jones (Paul Dano), but a lack of evidence forces his release.
