When Thaddeus is found badly wounded near a 19th-century Chinese town, miner Li Kung (Nguyen) and his wife Ah Ni (Yuan) offer him refuge. As he heals, he becomes entrenched in a conflict that pits the townsfolk against the evil Master Ho (Ng), his nefarious Beetle Clan and the terrifying Lord Pi (Tagawa). With Thaddeus at his side, the mild-mannered Kung transforms into a deadly warrior in this martial arts epic.
