The Way of the Spur.

Guerino, a cowboy from Italy, travels to Shanghai in search of his sister Elisa, who was working as a model in China but mysteriously vanished. In Shanghai, Guerino finds an unlikely ally in Jieikai, a local Chinese, whose girlfriend also mysteriously disappeared while working in the same modeling agency. During their search to uncover the truth, they are dragged into a dark world of criminality, corruption and human smuggling affairs. When things take a bad turn and innocent people start getting killed left and right, Guerino takes the matter into his own hands in order to save his sister before it's too late... Driven by his thirst for vengeance and his desire for justice, he vows to take down every single link to this chain of smuggling affair following his one and only rule: kick first, ask questions later.
