Young police officer Shane Cooper relocates to the small country town of Red Hill with his pregnant wife Alice to start a family. But when news of a prison break sends the local law enforcement officers — led by the towns ruling presence, Old Bill — into a panic, Shanes first day on duty rapidly turns into a nightmare. Enter Jimmy Conway, a convicted murderer serving life behind bars, who has returned to the isolated outpost seeking revenge. Now caught in the middle of what will become a terrifying and bloody confrontation, Shane will be forced to take the law into his own hands if he is to survive.
