Ah-fei and Dragon, students under the brother kung-fu masters Shorty and Uncle, are sent to clear the ghosts out of a haunted house. After a brief search, they soon find that the “ghosts” are nothing but props set up by a couple of con artists. After making quick work of the cheats, the fighting pair discover that there is actually a real ghost hiding in the house! Ah-fei and Dragon may have studied their martial arts well, but how do you beat up something that’s already dead?
