Ver Cuevana. Siu Sheung (Juno Mak) is a solitary and frustrated young man. He works as a delivery boy at a small noodle shop and lives with his mother (Pat Ha) in a large, dilapidated Kowloon housing estate. As a young boy he enjoyed nothing more than watching his favourite anime, Space Emperor God Sigma, and singing along to Leslie Cheung's theme song with his father.
