When police discover a young girl brutally murdered, brothers Joe Fairburns (Paul Bettany) and Chrissie Fairburns join their supervisor Robert (Mark Strong) to investigate main suspect Jason Buliegh, a local sex offender and social outcast.

Forced to release Jason from police custody, the Fairburns take matters into their own hands in an attempt to coerce a confession. All the while, Joe and Chrissie's father Lenny Fairburns (Brian Cox), the former chief of police, remains in the car, a quiet spectator to the fatal tragedy that begins to tear his sons apart. Unspoken secrets and unvoiced suspicions drive the ominous suspense as Joe spirals into an obsessive confrontation between crimes of the present and crimes of the past.
