Homicide detective Greg Bowker's wife Rachael is visiting a friend in the seaside town of Port Fairy when she is physically assaulted by her abusive first husband, Trevor Flynn, who is running a dubious housing development beside the nearby lough.
Incensed when informed of the assault, Bowker travels to the town, promising anyone who will listen that he's there to settle the 'Flynn problem' once and for all.
When Flynn's shark ravaged body washes up on the rocks and forensics indicate he's been murdered, Bowker's name immediately goes into the frame. He is suspended from duty and forced to take leave while his colleagues investigate Flynn's demise.
Did Bowker kill Flynn? And can he stay at arm's length from a case where he is the number one suspect?
