The emperor is getting paranoid, and orders a loyal subject toinvent an undefeatable weapon. The result is the infamous flying guillotine (did this thing really exist?). Of the soldiers training to use it, Chen Kuan Tai is the best, much to the jealously of the second-best at using it. Second best tries to frame Kuan Tai, who eventually leaves himself when he figures out the emperor is mad and killing innocent people. Kuan Tai starts a new life, complete with wife, but can't escape his past forever. His enemies come looking for him, and he must find a way to defeat the dreaded hatbox with teeth. Some people think it is stupid. I sort of like it. Not a lot of kung fu, but plenty of decapitation and blood-letting.
