In a small village, a young and gifted martial artist named Yang Lu Chan seeks instruction in a highly secretive and powerful form of Tai Chi. Born with a rare and visible anomaly shaped like a horn on his forehead, Yang possesses extraordinary fighting abilities that are fueled by the protrusion. After receiving advice from a dying master and failing to find acceptance in various schools, he is directed to Chen Village. The residents there hold the secrets to an exceptional form of Tai Chi, but they are bound by tradition to teach it only to their own.

Upon his arrival, Yang faces immediate rejection and multiple challenges as the villagers refuse to share their knowledge with an outsider, despite witnessing his impressive yet uncontrolled skills. Meanwhile, an ambitious foreign engineer, Fang Zi Jing, and his army of mechanical golems and steam-powered machines threaten the village’s way of life. Convinced that mastering Chen-style Tai Chi is his only hope, Yang persists and gradually earns respect and trust from some villagers, including the young and skilled Chen Yu Niang. As the mechanical threat looms larger, Yang must harness and refine his abilities to help the village fend off the impending danger.
