The movie opens to three guys walking across snow or sand, cannot tell from the VHS resolution. The narrator explains the Mongolians are the bad guys. Three guys arrive at a temple martial arts practice. Casanova is a deaf mute and acts retarded too. The guy in black has come to learn martial arts and he is a Mongolian. Cut to the head monk complains the students are weak. Aside, some students speak of stealing a golden Buddha. The master wants to use the Buddha to fund the war against the Mongolians. Eagle Han Ying, the Mongolian, joins with the three monks who want to steal the golden Buddha and claims that Casanova Wong is a fake and a spy.
That's enough for the story line.
Kin Jeong-Nan plays the female martial artist. I never liked her previous performances particularly with Jackie Chan but the real problem could be the character she played were simply annoying, not her.
The ending is totally stupid. I tried to ignore it and pretend it was a bad translation. Casanova has a solar powered fist. The final fight was a cloudy day so he did not have his super power. Yet, I could see their shadows as they fought. The sky was clear and blue unless Casanova looked up, then it was cloudy. What was the purpose of the stupid gimmick anyway? Just have the fight! I deducted a point from the rating because of this. Casanova Wong was one of the greats but this was one of his worst.
