Underbelly Files: Infiltration - Underbelly files season 1 (2011)

Colin McLaren was a Victorian detective with an appetite for hard, if not impossible cases and a reputation for thumbing his nose at authority. Strong, capable and not afraid to take risks, he pushed himself to the limit and hated the thought of failure. So when the chance came to go undercover with the Australian branch of the Calabrian Mafia, McLaren grabbed it with both hands and gave it his all. It would prove to be the most dangerous, exhausting, confronting eighteen months of his life and placed him the position of having to betray a man whom he had come to regard as a friend. But it was also the most thrilling time he ever knew and resulted in the biggest win of his career, seeing eleven of the country’s most villainous Mafioso sent to prison.
