While chasing an escaping suspect during a raid on a drug lab, Detective Mal Toohey (Joel Edgerton) is shot and saved by his protective vest. After celebrating, Mal drives home drunk and hits a young boy on a bike with his side-view mirror. He calls an ambulance, but denies any involvement in the accident. When honest young cop Jim Mellic (Jai Courtney) and his cynical older partner Carl Summer (Tom Wilkinson) arrive on the scene, Carl recognises Mal and sends Jim off to secure the perimeter. He questions Mal privately and sends him home, making Jim suspicious.
