The Brighton Mob (2015) online

Ryan is a well-intentioned, but troubled young police officer, just out of training. Senior officer, DCI Guy Sabo, singles Ryan out as a perfect candidate for undercover police work and sets about training him in the art of deception, how to immerse himself in the criminal underworld, and how to become someone else entirely. Ryan transforms into Max, a young criminal with a force-ten temper and soon finds himself crossing the line in order to infiltrate a notorious gang of bank robbers, headed by the enigmatic and elusive master-thief known only as 'the Monopoly Man'.
