THE ASYLUM SESSION

In a bleak and distant future, the last hope of tomorrow’s dreamers is a place they call the Asylum. When her father forbids her from becoming an artist, Hiyoko runs off to a tent city set up in an abandoned stadium called The Asylum. She meets other gifted youth there, and she finds herself and her purpose. But when profiteering officials and police plot to tear the Asylum down, they use art and culture to win the hearts of the people in a festival they call the Asylum Session.
