Seven years after the disappearance of baby Azaria Chamberlain at Ayers rock, long before the murder of Peter Falconio on a remote stretch of highway in the Australian outback and two years before Ivan Milat begins his murderous reign of backpacker murders, a silent killer is descending into madness in the wilds of Australia.

For the first time the complete story of one of Australia's most horrific serial murderers is finally revealed. Almost twenty years ago in June 1987 a crazed gunman begins a journey which will take him thousands of kilometres across the vast Australian outback. The killer's journey will result in the murders of five innocent tourists, spark one of the biggest manhunts in Australian history and end in a bloody last stand shootout with police at a remote outpost deep in the rugged Kimberly ranges of Australia's north. Before it is over, thousands of residents living in communities scattered across the country's Top End will be terrorised. Ordinary citizens will take extraordinary measures to arm themselves to protect their families from an insane murderer who appears to be hell bent on killing anybody who gets in his way. The first of the gunman's victims are a father and son who are cold bloodedly shot dead while scouting for a fishing location on the banks of the isolated Victoria River in the Northern Territory.
