The film opens with a retired Jackie Chan living a quiet life as an antique appraiser in Hong Kong, far away from the chaotic adventures of his past. However, peace doesn’t last long when a mysterious organization breaks into the museum and steals a set of ancient talismans believed to hold mythical powers. Jackie, reluctant but compelled by responsibility, is approached by a secret branch of global security who reveal that the talismans are connected to an ancient prophecy predicting the return of a forgotten demon emperor. Jackie’s knowledge of artifacts and history makes him the only person qualified to track them down.
Jackie pairs up with his witty and tech-smart niece Jade, now an adult and a rising field agent eager to prove herself. Their strained yet humorous mentor-student dynamic becomes the emotional core of the story. Jade insists she’s ready for real action, while Jackie, haunted by the danger-filled past, tries to protect her. However, the duo’s first mission takes them to Tokyo, where an underground syndicate auctions mythical relics to the highest bidder. A breathtaking chase across neon rooftops showcases Jackie’s classic martial arts mixed with practical stunts.
The antagonist is revealed as Draven Kane, a former archaeologist turned power-obsessed cultist who believes unlocking the talismans’ power will make him the next divine ruler. With mercenaries and dark magic on his side, Kane becomes a formidable threat. Jackie and Jade race from Japan to the Tibetan mountains and the jungles of Cambodia, uncovering traps, riddles, and mystical guardians. Each talisman retrieved reveals more supernatural elements, blending martial arts realism with fantasy adventure.
As Jade gains confidence and skills, Jackie confronts the guilt of past missions where he lost allies. Their bond strengthens when Jade rescues Jackie during a collapsing temple sequence, proving growth and earning his respect. Together, they decode the final riddle pointing to the Valley of Shadows, the location where the demon emperor was sealed centuries ago.
The climax unfolds inside an ancient fortress during a lunar eclipse, where Kane attempts the ritual that will merge his body with the emperor’s spirit. Jackie fights through enchanted warriors while Jade disables the ritual machinery. In a symbolic moment, Jackie sacrifices one talisman to save her, accepting that the future belongs to the next generation.
The film ends with Jackie returning to his peaceful life, though this time with pride in Jade’s new role. Jade receives a call hinting at remaining mystical artifacts still scattered around the world, setting the stage for future adventures as Jackie smiles knowingly, aware that the legend is far from over.
