Kung Fu Jungle

A vicious serial killer Fung Yu Sau is going around Hong Kong and killing top kung fu masters, leaving a secret weapon called the Eaves Swallow as his calling card. When a convicted killer and kung fu master, Hahou Mo, hears of this, he offers to help the police catch the killer in exchange for early parole. With Hahou Mo’s help, Inspector Luk Yuen Sum comes to understand that the order the serial killer targets his victims and his MO are both based on an ancient code of kung fu training. When Hahou Mo violates his parole and disappears, Luk Yuen Sum suspects that Fung Yu Sau is working with Hahou Mo as a bait for the police to spring the later out of the prison.
