In St. Tropez, the orphan Juliete Hardy is an eighteen years old woman sexually active and ahead of time, strongly desired by the wealthy middle age man Eric Carradine.

She has a crush on Antoine Tardieu, the older son that works in Toulon of a poor family that owns a modest shipyard, but he just want to have one nightstand with her.

When Juliete's stepparents decide to send her back to the orphanage because of her bad reputation in the town, Antoine's brother Michel Tardieu proposes to marry her and she accepts, and she begins to love him.

But when the Tardieu family decides to sell the shipyard to Eric and Antoine returns to St. Tropez, her lust for him blossoms again and becomes an announced tragedy.
