Young actress Lindsay Scott can hear everything anyone says about her. One day, Lindsay decided she couldn't take it anymore and quit the actress business. Now, she stays in the safety of her home, the only place where she can live in peace and quiet without the voices.
One night, two fans come to Lindsay's house and kidnap her, thinking they are rescuing her from her father, who, as the newspapers say, is holding her hostage. When Lindsay finally explains that what they heard is not true and gets home, their friend is still worried about her. Will Lindsay ever have a normal life? Will she find out why she hears voices?
