Underdog Knight - Chinese Movie with English Subtitles

Underdog Knight is a Chinese martial arts movie about a young naval officer who suffers a mental injury and is discharged from the navy... only to become a vigilante protector of the common people, fighting "evildoers", thieves and the mafia.

I also find it interesting because the villains in the story are after a famous historical spear made from meteorite.

I give it four stars out of five. You can watch it on YouTube for free, with English subtitles.
