I hope I am doing this right! I am trying to find the movie with this story. A teenager works at a restaurant - pizza place I think. He has a stepdad and 2 blonde stepbrothers. The stepdad is trying to make the 2 stepbrothers into singers. The teenager working is kind of like Cinderella. He ends up entered in a singing contest, but his stepdad locks him in a closet but he finally gets out. There is also a girl in the movie who sings. That is all I can remember! My 8 yr old loved the movie and we are trying to find it for him. Thanks!!
