Like The Flying Guillotine, the title here refers to a deadly decapitation weapon. The dragon missile is two boomerang swords that spin, hover and grind their way through stone, trees and skulls. Lo Lieh is at the center of the story and it’s unclear as to whether or not he’s the bad guy or a good guy trapped in a bad job. That is until his cuts off his mother’s head. From then on, seemingly minor characters are now the heroes as they try to enact revenge. The story has a weird structure, but it’s pretty simple and it keeps the stakes high as character’s heads get sheared off one-by-one.
