When Detective Inspector Carol Ashton is called in to investigate Captain John Trelawney's fatal fall from Sydney's scenic North Head, she discovers that his brutal demise may fit into a disturbing state-wide pattern of apparently accidental deaths. Carol's suspicions are heightened when a closer look at these "accidents" reveals that they effectively eliminate a problem person and provide a substantial insurance payout. But before Carol can catch the killer she must prove that these seemingly unrelated deaths are, in fact, murder and very related.
