A common American elementary school. A long corridor full of lockers where children put their things. Instead of the pupils, though, there are multicoloured backpacks bouncing around as avatars. And three of them want to play basketball in the gym. But who is usurping the whole gym for themselves, not allowing the others to touch the ball? The socially-themed project by Venice award-winning director Van Phan focuses on the topic of school bullying and explores how it can be prevented.
