Jean-Paul and Marianne, who are in a romantic relationship, are taking pleasure in a carefree and joyful vacation this summer in a gorgeous property located close to the sun-drenched town of St. Tropez. The only thing that matters to them is indulging in their shared sexual need — that is, until the day that Marianne invites her ex-lover and the man's stunning daughter to spend some time with them. It doesn't take long for the four of them to start feeling uncomfortable with one another and the atmosphere quickly elevates into a potentially hazardous love triangle.
