A sequel to the successful, 2003 action fantasy Twins Effect in name only, this stylized, special effects-heavy martial arts adventure finds a humble boy embarking on an epic journey to claim his rightful position on the throne of a vast kingdom. Enraged by tales of a young warrior who legend states will rise to end her diabolical reign over Huadu, the wicked Empress (Qu Ying) and her eunuch high priest (Daniel Wu) dispatch skilled assassin Blue Bird (Gillian Chung) to prevent the prophecy from coming to pass. Later, Blue Bird clashes swords with irritable slave trader 13th Young Master (Charlene Choi), but the two rivals decide to join forces after realizing they have a common goal. When Blue Bird and 13th Young Master cross paths with Blockhead (Wilson Chen) and Charcoal Head (Jaycee Chan, son of Jackie), they realize that one of the boys is the one prophesized to wield the mythical sword Excalibur, and defeat the evil Empress. Upon realizing that Charcoal Head is the legendary warrior in the flesh, Blue Bird and 13th Young Warrior join him on his treacherous quest to become the rightful ruler of Huadu.
