Coming-of-age mystery thriller starring Shailene Woodley and Eva Green. After her mother (Green)'s sudden disappearance, 17-year-old Kat (Woodley)'s steady home life is unexpectedly thrown off balance. But rather than grieve, Kat surprisingly grows to love the newfound freedom offered by her father (Christopher Meloni) and relishes the opportunity to embrace being a wild teenager, going as far as seducing the detective (Thomas Jane) working on her mother's case. But years later, as the mystery remains unsolved and no reasonable explanation unearthed, Kat digs a little deeper into events surrounding her mother's disappearance and discovers she may have been repressing the truth about how much her dysfunctional family and the void of her mother has affected her all along.
