Paul Bryan tags along on a cruise, with his gigolo pal Ramon and two beautiful women targeted by Ramon. Target number 1 on her royal yacht, is Princess Ingrid, immediately smitten with the irresistible dying attorney. The secondary mark, Rachel Pike, is repulsed by Paul's macho smugness. Paul discourages the vulnerable princess, who the sensitive Ramon agrees to let down easy, per his usual MO, pretending to be a wealthy Andorran sheep baron, who will suddenly have a cash crunch.
A mysterious scuba diver drags a beautiful woman underwater to her death, and Paul Bryan is asked by her twin sister to investigate, because the Milan polizia rule the death accidental, though the victim was a strong swimmer. Bryan poses as an insurance investigator, because the woman's policy has a double indemnity clause, and she was in the midst of a divorce, planning to wed an industrial titan. Her estranged husband, philandering playboy Chips Harley, claims they were going to reconcile, so it wasn't him, but he happened to also be in Milan that day.
