Juliette, an 18 year old orphan with an unbridled sexual appetite, causes quite a stir with her behavior, attracting the attentions of men. Her first suitor is the much older Eric Carradine, a rich land baron set on building a new casino in town. His plans are being hampered by the Tardieu family that owns a small shipyard on the stretch of land he requires for his development. Michel, the eldest Tardieu son, returns home for the weekend from Toulon to discuss the situation and finds Juliette anxious to pair up with him. His intentions for Juliette, however, are very short term, and he spurns her by he leaving town without her. Juliette's guardians have had just about enough of her antics, and threaten to send her back to the orphanage.

To keep her in town, Carradine pleas with Michel to consider marrying her, which he laughs off, but his naive younger brother Antoine rises to the challenge and proposes. Despite being in love with his older brother, she accepts. When Michel is contracted to return home for good, the trouble starts for the newlyweds, and all the men in her life come to realize just what she means to them.
