From Brisbane's sleazy Sin Triangle to drug busts in the wild far north, former undercover cop Domenico 'Mick' Cacciola tells his incredible tale of underworld crime and police corruption.

After joining the Queensland Police Force in the 1960s, Mick risked his life infiltrating illegal gambling dens. In the 1970s he saw the ugly face of entrenched corruption in the seedy Licensing Branch, waging a long and bitter battle with now disgraced police commissioner Terry Lewis and the infamous bagman Sergeant Jack Herbert. From Special Branch hard-man and bodyguard to a detective investigating some of Australia's most brutal murders, Mick's career was a white-knuckle ride until he retired in 2001, never letting up in his fight against standover men, violent crims and cops on the take.
