Tiger Cage

Inspector Michael Huang, alongside Shirley Ho, Brother Lung, Fan Chun-yau, Uncle Tat and Terry are all part of the Anti-Drug Unit of the Royal Hong Kong Police Force. The relationship between them are like brothers in general. During an operation, they worked together to bust a drug den but the chief drug trafficker, Swatow Hung, escaped. Just as they were celebrating their success, Hung found them and killed Lung. In order to avenge Lung and find Hung, they took a variety of means and finally found and killed Hung. During an accident, Yau filmed Tat trading with a drug trafficker and tells Terry and Michael. After Michael found out, in order to protect himself, he killed Terry and framed Yau, who was then suspended from duty, which caused Yau to feel suspicious.
