A Chinese transplant surgeon is running a widespread people smuggling operation throughout South East Asia, mainly for the purpose of supplying body parts to his ultra rich clients. The operation falters when the surgeon uses a hydrofoil belonging to Kate Savage in which to ship refugees from Vietnam to China.

When Kate investigates anomalies in her recently acquired ferry company, a close colleague is murdered and she narrowly escapes being one of the surgeons donors.

Kate's eventual rescue from the island of Hainan is brought about by a middle aged civil engineer and three elderly ex Ghurkha soldiers. These four rugged individuals, eventually cause the downfall of the surgeons corrupt regime.
