One summer, this seventeen-year-old boy (played by Angarano) rode his bike to a pawn shop in Boston's Chinatown, looking for collectible Chinese kung fu movies. However, he always ran into trouble when going through the alleys near his home because Jason was often targeted and bullied by a group of hoodlums. Jason was an expert at video games and knew all about kung fu films; he always wished that he could become a kung fu master too. However, Mr. Ho, the owner of the pawn shop, thought that Jason wasn't cut out for it since he didn't even know what kung fu really was. One day, Jason accidentally discovered a mysterious golden cudgel in the pawn shop, which allowed him to pass through the "gate without a door" and travel to ancient China! He found himself in the middle of a stunning prophecy: a messenger must return the legendary weapon to its rightful owner.
