Four Riders(四騎士)

This prime example of director/co-writer Chang Cheh's mastery takes place in Seoul right after the Korean War, as a kung-fu master, combat instructor, explosives expert, and missile specialist must take on a venal drug smuggling gang. Representing the Book of Revelation's four riders of war, famine, disease, and death as heroes against murder, corruption, jealousy, and greed, it's a brutal battle where the one true winner is the audience.
