This time on Australia’s Most Dangerous Prisoners we meet Paul Denyer, the deranged serial killer who has been deemed too dangerous to release from jail… ever! Then there’s the irresistible Black Widow Michelle Burgess who is serving a 30-year sentence for callously plotting the murders of her husband and her boyfriend’s wife. Matthew Johnson is the career criminal turned murderer in prison, who bludgeoned a fellow prisoner to death with a bar from an exercise bike. And Corrections Officers share their stories of the extreme violence they witness and experience while guarding Australia’s Most Dangerous Prisoners.
