In the late 1990s, a string of disappearances in Rockhampton, Queensland leave police searching for a killer they can't identify. The murder of a 9-year-old girl on her way home from school blows the case wide open when ex-con Leonard Fraser is arrested and convicted for her murder. Without the evidence to connect Fraser to the other disappearances, however, police must rely on one of his fellow inmates to get the truth from Fraser.
