Sebastian (Asa Butterfield, Ender's Game) is a sixteen-year-old who has spent most of his life with his Nana (Academy Award®-winner* Ellen Burstyn, Requiem For A Dream) in their geodesic dome home, a tourist attraction where she raises him on the futurist teachings of her former mentor Buckminster Fuller in hopes that one day Sebastian will carry Fuller's torch and make the world a better place.
