Detective Darren Glass is back, and the stakes are higher than ever.

When the battered body of a young Aboriginal woman washes up onto a beach at Jervis Bay, Australian Federal Police Detective Darren Glass is brought in from Canberra to investigate.

Glass quickly ties the murder to the disappearance of a sailor from the nearby naval base, and is forced to partner up with a senior intelligence officer from the Royal Australian Navy.

Together they follow the trail of evidence to the red heart of Australia, where a confrontation with outlaw bikies and Aboriginal activists proves deadly. As the body count mounts and foreign links emerge, the conspiracy at the heart of the case becomes a threat to Australia's national security, as well as regional peace.
