The setting is post-war Korea. The four main characters are played by four-fifths of The Savage Five (another fine movie). We follow these characters into the world of vice and easy money, as represented by a local bar frequented by ex-military types. Japanese actor Yasuaki Kurata is perfectly cast as the owner of Hello John (a nice dig at strangely translated goods and services in some Asian countries).

The action is great, the acting is very good, and it's always interesting to see how Shaw Brothers pulls off movies that feature a more modern setting. With Four Riders, I think they made a real winner.
