The Invisible Man

A group of homeless aliens begin to migrate illegally to a small town on Earth. A young guy Wang Er Gou with invisible powers is supposed to stop the invasion, but instead he is mistaken for an alien. An evil biologist kidnaps the hero and begins experimenting on him. When the aliens decipher Wang's invisibility, they send Brain, an experienced retired general and an alien with invisible superpowers, to challenge him.
