UNDERBELLY: Badness chronicles the spider web of criminality spun by Anthony Perish and the quest by a dedicated team of police to bring him and his associates to justice. A feared underworld figure, Perish managed to maintain an almost non-existent public profile, which was only revealed when his connection to the murder of Terry Falconer, a former inmate of Sydney's Silverwater jail, brought him to the attention of Strike Force Tuno, which was formed to find Falconer's killers. Displaying an extraordinary level of perseverance and determination, Strike Force Tuno, led by Detective Inspector Jubelin spent ten years gathering the evidence that would finally see Perish brought to justice.
