Silkie Trevor isn't keen on her new P.I. assignment. She's not a prude, but being ordered to seek out a nameless man with an anchor-shaped birthmark on the most private part of his body isn't something she really wants to do. In order to find her man, Silkie must travel to Mistral Cay, a Caribbean nudist colony catering to rich, privileged women whose every fantasy is granted by handsome young men with chiseled pecs and washboard abs. To find the man she's after, she will be required to inspect the "packages" of each of the handsome gigolos working at the Cay.

Julian St. John is intrigued by the latest arrival to his lush tropical paradise. The honey-blonde beauty with the fascinating green eyes is there under the guise of doing "research" for a long-time client of Julian's—Dr. Olivia Carstairs, the noted urologist. But St. John knows she's there for another, more private reason.

Determined to have the petite woman for his own, he sets out to win Silkie's heart while she's looking for one particular body among his well-trained male escorts.

It's a hot, hands-on job that will make Silkie and Julian sweat!
