Long ago, Meston Park in Brisbane's West End marked the city's boundary. A curfew kept its Aboriginal population outside the city limits after dark. When the park becomes the site of a multi-million dollar development, the Corrowa People vow to fight and file a native title claim. Hours after rejecting the claim, Justice Bruce Brosnan is brutally murdered. Some believe it is the work of an ancient assassin, returned to destroy the boundary. While the investigation forces Detective Jason Matthews to confront his buried heritage, lawyer Miranda Eversely battles a sense of personal failure at the Corrowa's defeat. How far will it take her to the edge of self-destruction?
