Garth goes undercover as a security consultant to track down Eva Richardson, the mind behind a powerful vice ring. He uncovers a link with the drug squad and, after one of Eva's girls is discovered dead in suspicious circumstances, an internal investigation is launched with results in Liam being posted back to investigate his old drug squad colleagues.
