Synopsis by Hal Erickson
The Four Assassins in this kung-fu effort are brothers. As the title indicates, these siblings aren't to be trifled with. Their courage and strength is tested to the utmost when they run up against a wicked Mongolian emperor. A full cast list has yet to be found: we do know that two of the brothers are played by Yuan Lung and Chai His Fan. Also starring is Richard Harrison, hero of many a sword 'n' sandal pic of the sixties and seventies.
