South China Sea, 1995. Pirates rule the waves and ships are disappearing in deadly ocean blackspots. To combat these cut-throats, a SBS team is sent to Singapore to play a game of high-stakes hide-and-seek across the tropical seas, picking up a trail which leads them north towards Hong Kong.
Meanwhile, as the Communist Chinese takeover looms for the British colony, Inspector Rosalie Kai is investigating a barbaric cross-border trade in unwanted female babies. Soon both she and the SBS team find themselves in the underworld jungle up against a criminal organization that stretches from one end of the South China Sea to the other, fighting rogue elements of the Indonesian Army, corrupt policemen, and the foot soldiers of the fearsome Triads.
