They were a ship of sinners who left their morals on the pier.

CABIN 15A ROBIN & SHERRY—
Two call girls who played for pay, but when they played for keeps they played with each other.
 
CABIN 17A LETTY—
A technical virgin who won her ticket on a quiz show by not being so technical about her virginity.
 
CABIN 18A VIVI —
Sex mistress of the ship, she knew what men and women wanted—and gave it to them from stem to stern.

CABIN 19A JASON & CONNIE—
He had the equipment, she knew how to use it.

Then there was Alan and Owen and Martine, all thrown together on a cruise that was one wild orgy from port to port.
