In Hong Kong, a rare treasure is stolen by oil tycoon Victor Hess, and in Rome, Willem Van de Post plots with a powerful ally to get it back. The intrigue continues when the Gypsies hire DKA to find their princess, and a German baron contracts the firm to test defenses at Hess' mountain fortress. No one is who they seem to be, but they all have one thing in common. They're all scamming their way to Rome, where a spectacular con is about to explode with deadly finality.
