Teenage Kira attempts to take revenge after a heartbreaking betrayal by her ex-best friend. This tense drama from filmmaker Laurel Parmet renders its highly charged atmosphere with complexity and restraint. Similar to her previous short, “Spring,” which found an impromptu photo shoot between two teen friends turning racy, “Kira Burning,” explores matters of sexuality and young female friendships, their questionable behavior shown with real-time fallibility. After her old friend Ruby posts a sexually forward video of her on Instagram, Kira and a couple friends break into her house aiming for payback. Showing just how cruel and emotionally volatile teens can be, scarily enhanced by the modern age’s ability to publicly humiliate via social media, the riveting sequence is delivered with highly believable performances and isn’t afraid to follow its characters over the edge. (8 minutes). Directed by Laurel Parmet. Produced by Lisa Duva. D.P. Brian Lannin.
