A brutal end of innocence for 1960s Perth, Australia, when a series of seemingly unrelated murders shocks a tight community.

When yet another horrific killing terrorizes the community and a man stands trial for killing his girlfriend, police set a cunning trap for an elusive killer.

Eric Edgar Cooke had been caught, but the true extent of his crimes and their lasting effects on the innocent take years of determined investigation to bring to light.

Once it had been determined that John Button was innocent, the review of Darryl Beamish's case revealed gross corruption by the police, and he was pronounced innocent as well. But the legacy of the brutal crimes - for the victims, the innocent, and the real killer's family - continue to this day.
