The Secret Life of Zoey (2002)

She thought she knew everything about her daughter.

Marcia always thought her overachieving daughter Zoey was the dream child. But then she discovers that her perfect teen has a not-so-perfect drug addiction. Marcia and her ex-husband go through plenty of denial as their daughter spirals out of control. It's a true-to-life tale that parents and their kids should watch together.
