Cally (Clea DuVall) is a moody, melancholy 17-year-old who was raised on a small commune by her father, Wade (Tomas Arana). She's never met her birth mother, but one day at a music festival Cally sees a free-spirited older woman, Sabine (Daryl Hannah), and becomes obsessed with the idea she is her mother. Cally tracks her down via a sketchy drug dealer (Eric Roberts) and throws herself into Sabine's life. Are her instincts correct? Or is Cally deluding herself?
