Siblings Yan Fei (Michelle Yeoh) and Yue Tong (Brandon Chang) are the star performers in a traveling acrobatic troupe. One day, Eric (Ben Chaplin), a man who had apprenticed with their late father, shows up in possession of a storied ancient artifact. After Yue Tong pilfers the item and heads for the countryside, his sister and Eric give chase, but soon realize they are being pursued by wealthy art collector Karl (Richard Roxburgh) and his murderous goons.
