It’s the Sung Dynasty versus the Chin invaders as the “Iron Triangle” of director Chang Cheh and stars David Chiang and Ti Lung truly hit their stride with this crowd-pleasing kung-fu epic. When a handsome Prince is taken captive and guarded by a martial arts master, it’s up to two powerful patriots to fight overwhelming odds to pull off the impossible: rescue the royal son and get out of the Chin stronghold alive. It’s action as only Chang can film it, with supremely charismatic acting and fighting as only Chiang and Lung can perform it. From the first fascinating minute to the final desperate battle to the death – culminating in an unforgettably evocative conclusion - this duo is dynamic as well as deadly.
