The source of the commotion is a group of men pursuing a young woman who is swimming frantically away from the other ship. Templar rescues the woman who, after some considerable hesitation, identifies herself as Loretta Page, a private detective who is investigating the mysterious disappearance of sunken treasure from the Atlantic. When she learns her rescuer is The Saint, she enlists his help in tracking down a group of modern-day pirates. These pirates, led by Kurt Vogel, are using newly developed bathyscape technology to reach the sea floor and scour recent shipwrecks for gold and other booty before officially sanctioned salvage operations arrive. And Vogel is not against committing cold-blooded murder to keep his operation going.
