Charismatic Julia, who just moved into Diane's neighborhood, exudes independence, spontaneity, and an adventurous spirit? everything that Diane seems to be missing. Willing to go to any lengths to break the chains of childhood, the two girls set out to experience nightlife, men and sexcapades that would make their parents blush. As they grow closer, Diane and Julia say goodbye to morality and hello to a life of unbridled desire.
