In Australia, there are over 40,000 men and women currently behind bars. Many of them have done very bad things. They have shattered countless lives, destroyed families and been responsible for unspeakable criminal acts. What did they do? How did they get here? And what are their lives like now? The gripping new series will outline in detail the horrendous crimes that landed these men and women in Australia’s high security jails through first-hand accounts by ex-inmates, former correctional officers, journalists and forensic psychologists, who try to make sense of their world. Australia’s Most Dangerous Prisoners is a WTFN production for the Seven Network.
