Rachel Watts is suffering from recurring nightmares about her near-death experience in London. She just wants to forget the whole ordeal, but her boyfriend, James Mycroft, is obsessed with piecing the puzzle together and anticipating the next move of the mysterious Mr Wild - his own personal Moriarty.

So when Rachel's brother, Mike, suggests a trip back to their old home in Five Mile, Rachel can't wait to get away. Unfortunately, it's not the quiet weekend she was hoping for with the unexpected company of Mike's old school buddy, the wildly unreliable Harris Derwent.

Things get worse for Rachel when Harris returns to Melbourne with them - but could Harris be the only person who can help her move forward? Then a series of murders suggests that Mr Wild is still hot on their tails and that Mycroft has something Wild wants - something Wild is prepared to kill for.

Can Watts and Mycroft stay one step ahead of the smartest of all criminal masterminds? The stage is set for a showdown of legendary proportions.
