Film Synopsis

Clémence's work as a family court judge has made her pathologically suspicious of the opposite sex.  Even though her relationship with her present boyfriend Gabriel could not be more secure and harmonious, she fears that he may be susceptible to affairs with other women once they have married.  So, on the eve of their wedding she hires an attractive young red-head, Olivia, to put her partner's fidelity to the test.  With Gabriel away on a business trip on the island of Réunion, Clémence sends Olivia to join him and subject him to her obvious feminine charms.  Things take an unexpected turn when Gabriel's American client mistakes the vivacious red-head for his wife.  Without meaning to, Clémence has created the very situation she had hoped to avoid, thrusting into the arms of her future husband a rival that threatens her dreams of marital bliss...
