Lucie, who works as a white-hot fashion model, exhibits a dominant, often controlling, "Type A" personality, whereas identical twin Marie consistently projects a backward, reserved, laconic and unassuming attitude.

Marie possesses the voice of an angel, however, and quickly jets off to Paris to stand in for her sister, unannounced - little realizing the dangerous and even violent string of consequences that she is igniting.
