A well-known theater director is waiting for his female lead to sign her contract for his new play. She's late after picking up her sick daughter at school. Despite her enthusiasm for the project, it turns out the contract is not what she expected.

Two crooked lawmen (Stomy Bugsy, Titoff) search for a precious stone to collect an inheritance.

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. When Lucie receives a covetable French recording contract, a significant problem stands in her way: the inability to sing. 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.
