Gritty. Laurel loses her mother and grandmother in a flood. After living with her aunt for a couple of years, she moves to a little town called Galilee with her father and brother. Now 15, she becomes a cheerleader and starts dating the star basketball player. Unfortunately, T-Boom introduces her to meth ("moon").
From there her life slowly disintegrates. Her dad is still too grief-stricken to notice, but her best friend Kaylee does and tries to help. Laurel turns away from her, and when her dad finally finds her stash she claims it is Kaylee's. Dad takes it over to Kaylee's mom to narc on her, finally gets the clue-by-four that his daughter has been using right under his nose.
Laurel runs away and starts panhandling to try to get her fix. Her only friend is Moses, who makes a living painting murals of deceased drug addicts for their families as part of an anti-drug campaign. He warns her about the hazards of meth but still gives her $3. When she asks him why he did it when he knows she's going to buy meth, he tells her it's an investment because he'll get $100 from her dad to paint her mural in a few months when she's dead. She knows he's right; part of her is aware of the damage she's doing to herself while the rest just craves the next dose of moon. It's a struggle as to which side will win in the end.
