Vigilante justice carried out by the police. A terrified witness with nowhere to hide.
Three police officer brothers are killing criminals that have avoided justice for their crimes due to technicalities.
An innocent bystander, Mike Hendy, accidentally witnesses their latest brutal execution and is immediately thrown into a harrowing game of cat and mouse with the brothers. They know who he is and they watch his every move as Mike struggles to find someone to trust who can help him.
DS James Ripley and DC Coffey might be his only hope, but their investigation unearths an even bigger conspiracy that sets off a chain of events with shocking repercussions for Mike, the brothers and the detectives.
