Wallflower

On the night a disturbed man from a small town plans to commit a mass shooting at a Seattle rave, he is befriended by an eccentric group of ravers who invite him into their home. As the night unfolds, he finds himself conflicted about his intentions as the lines blur between their liberated world and his repressed desires. WALLFLOWER is a clash of civilizations: the old America versus the new.
