After catching her boyfriend cheating, Amanda (Bárbara Mori) decides her good looks are causing the problems in her life. She moves to a new town and creates an unattractive alter ego to ward off men and gain respect from her co-workers. When she meets Marcelo (Marcelo Mazzarello), a self-proclaimed womanizer, Amanda's anger inspires her to teach him a lesson using both her "ugly" persona and a provocative third personality named Helena -- but leading a triple life isn't easy.
