[1] It stars Beth Howland, Katherine Kamhi and Ian Ziering.
Hard-working 16-year-old Julia does not realize that her mother Eleanor - who alternately harasses and ignores Julia, while doting on lazy younger daughter Katie - is being emotionally and verbally abusive.
But when Julia is given the lead in a school play directed by popular Randy, she realizes she is every bit as worthy of Eleanor's support and encouragement as her pampered sister.
Julia gets Eleanor to open up and find out where her anger comes from.
