For most of Lucy's life, it's just been her and her mom, and Lucy's been okay with that. But when a serious illness strikes Lucy's mother, Lucy has to grow up faster than she expected. As the illness gets worse and money gets tighter, even a school trip-which Lucy hoped would give her a break from home-seems out of reach. Out of frustration and desperation, Lucy starts selling her mom's medical marijuana. But she's not exactly an experienced dealer. And when Lucy gets busted, she has some serious explaining to do to school authorities, to the police, and to her mom.
