Sixteen-year-old teens Abby and Leila are "pot addicts." When their parents lose patience with them, they are sent to Tall Pines, a juvenile detention center in rural Oregon run by an unregulated cult—with Leanne as head youth counselor. At the same time, Detective Dempsey moves to Tall Pines at the request of his wife, who grew up there and wants to return home to raise their upcoming child. But when Dempsey discovers the truth about Tall Pines, she will have to work with the teens to fight the evil from within.
