A man dies after being dunked in a vat of toxic chemicals. A ship explodes in Port Phillip Bay, leaving a poisonous fallout. A pall of black smoke hangs over Melbourne's western suburbs as Jack Speerman begins his investigations into a cover up of lethal proportions. As Jack digs deeper, he unearths everything from crooked horse racing and money laundering on the trail of an illicit trade in chemical weapons, made right in Melbourne's own backyard. The stakes are high and the bodycount is even higher on a switchback ride of cross and double cross. Vengeance is a game no one can win. Jack just has to survive.
