Lorraine has a phenomenal voice, but little faith that superstardom will beckon whilst working as a checkout assistant in her local supermarket.
Her luck changes when, unbeknownst to Lorraine, rather dubious circumstances create an opportunity for her to become her idol's stand in. Lorraine not only gets an entree into the life she could have, but also an introduction to Danny, who is handsome, rich and very interested.
But all is not what it seems. This opportunity sets in motion a chain of events that bring her closer to achieving her dream, but further away from reality and the truth.
Lorraine learns very quickly that there's no such thing as a lucky break.
