This film is about the life of socially deprived people who lives in caged housing in Hong Kong. Given the very tough topic of social deprivation, extreme poverty and shockingly appalling living conditions, I expected "Cageman" to be very tough to watch. This turns out not to be the case. Instead, "Cageman" is a warm, positive and loving film about friendship. People in the caged housing live as harmonious as possible, supporting each other by their limited means.
