In a dreary English seaside town, one of it's timid inhabitants, known as LV (Little Voice), mourns over her dead father and obsesses over his record collection by singing along to his favorite performers. Her rare talents for emulating the dulcet tones of Judy Garland, Marilyn Monroe, and Shirley Bassey are soon discovered by her dominant mother's boyfriend, a small-time showbiz agent. Their attempts to propel her to stardom are at first successful when the local town gets to see her perform. However, LV is soon wise to their selfish intentions and withdraws from performing again, thus forcing an emotional showdown between the three.
