In this sexy, French romantic drama (previously titled Happy Few), two couples decide to explore the boundaries of their relationships by swapping partners. What starts as a fun, free-spirited ménage-a-4 experimentation full of sleepovers, shared vacations, and dinner parties soon turns into a hotbed of desire, anger, and confusion. As their arrangement leads them down an increasingly surprising and provocative path, the lovers begin to question their personal choices and lifestyles, leading to consequences none of them could foresee.
