While international favorite David Chiang was best known for his roles as a grinning, streetwise, fighter in many Chang Cheh-directed classics, he rarely played a noble warrior monk. But here he portrays the great Chih Shim, the monk who saved the Southern Shaolin Temple. Making this production all the more notable is Lo Lieh, Shaws' first international star, who returns to a role he also made famous - that of Shaolin renegade Pai Mei. This, and even more, makes for a true martial arts epic of the first order.

Bruce Lee has just died, but the BSI is swinging into action to salvage the situation. Aided by the brilliant Professor Lucas, cells from the martial arts master's body are removed and grown into three adult Bruce Lee clones. After undergoing training to bring their skills up to the level of their 'father', the three are sent out to battle crime, with one sent to take on a gold smuggler, and the other two teaming up to shut down an evil mad scientist.
