Underbelly: A Tale of Two Cities is the true story of how two men changed the face of organised crime in Australia. Aussie Bob Trimbole and Kiwi Terry Clark are an unlikely pair. One an overweight Italian-Australian who loves his food and marijuana crops; the other a charming young New Zealander, in love with money, power and the allure of beautiful women. Together, they mastermind the large-scale importation and distribution of heroin into Australia. The easy success of their plan instead results in the underworld becoming awash with drug money and a shift in the nature of organised crime in Australia. For a time, they get away with murder - lots of it. But not every cop in NSW and Victoria is corrupt, and when the Commonwealth Police join forces with their State counterparts, they place heavy heat on the Organisation's members. All it will take is for the Organisation to get sloppy, and for somebody to spill the beans...
