For 11-year-old Robin (Darcey Ewart) and the other kids in her suburban neighborhood, the forested area behind their cul-de-sac had been where they could play and let their imaginations run free with heroic fantasies. When a determined developer (Naomie Harris) looks to turn their play site into commercial property, the children might just have found a real-world nemesis to rally against. Charming family offering from Britain co-stars Gwendoline Christie, Mark Williams, Morgana Robinson. 100 min. Widescreen; Soundtrack: English.
