Jean Blake is drawn into the investigation of several bizarre murders whose only connection seems to be a series of articles recently published in The Courier about Ballarat's most infamous unsolved mysteries. It's a mad, mad world. President John F. Kennedy has been assassinated; the world has changed and tremors are being felt even all the way in Ballarat where Jean Blake (Nadine Garner) is unexpectedly drawn into the investigation of a pair of murders. No one knows the town's history better than Jean and she's determined to help, despite push back from Chief Superintendent Matthew Lawson (Joel Tobeck). Jean's whole world has fallen apart with Doctor Lucien Blake missing, presumed dead. But that same inner strength which got her through the losses of war and enabled her to raise two sons on her own will not allow her to be defeated. Ably aided by friends Chief Superintendent Matthew Lawson and newly appointed Police Surgeon, Doctor Alice Harvey (Belinda McClory), Jean is about to throw herself back into a world she thought she had left behind.
