The three 6-year-old girls who make up the Pink Helmet Posse, profiled in a short Op-Doc in The New York Times that also screened at Tribeca, are equal parts adorable and badass. The film opens with the three friends, Relz, Bella, and Sierra, painting their nails in the middle of a skate park. Next, we see them dropping into a half-pipe and maneuvering around a pile of leaves.
