Dale (GUY PEARCE), Mal (DAMIEN RICHARDSON) and Shane Twentyman (JOEL EDGERTON) are three brothers in prison for armed robbery. When they're let out, they immediately pull another job, but it's not long before they're picked up by detectives Mick Kelly (VINCE COLOSIMO) and Jack O'Riordan (PAUL SONKKILA).
Although they end up taking the three back to prison, they're actually in cahoots with them and the brothers' corrupt lawyer, Frank Malone (ROBERT TAYLOR). He wants them to pull one last job from which they can all retire, but Dale is reluctant. After all, he's pretty sure that his wife, Carol (RACHEL GRIFFITHS), is having an affair with Frank.
Nevertheless, and to get out of prison again, he and his brothers agree to set up the next heist. The only catch is that Frank has introduced two new partners to the team, Paul (KIM GYNGELL) and the tightly wound Tarzan (DORIAN NKONO). The brothers again reluctantly agree to the change in plans, but when their lone rule of no one getting hurt is broken, they decide to hit the road for good.
Yet, Frank isn't one to give up so easily and he sets out to find the three and their stolen money. From that point on, it's anyone's guess about who will eventually get the upper hand and the last word.
