The rich Chinese banker Wong dies during a bank robbery in California, when Dakota robs him too and takes 1000 dollars and four photos of women from him. The Wongs family is in China in the grip of a warlord who entrusted all his money to Wong, who was to invest it profitably in America. In order to save the family's life, the young Wang Ho goes to America. A found note tells him that the way to a treasure is tattooed in Chinese letters on the buttocks of four young ladies who make Wong's life sweeter. Wang Ho frees Dakota from the prison where he had been thrown in the meantime and, with the help of numerous tricks and after some dangerous adventures, sets out with him to find the four women.
In Margheriti's hands, the film becomes a spaghetti kung fu that should not be missed. Of course, there have already been Terence Young's "Rivals Under a Red Sun" and Mario Caiano's "My Name is Shanghai Joe," but here the Shaw Brothers come to Italy with their biggest star Lo Lieh for a co-production. Obviously, the greater resources at the director's disposal do not automatically mean that the film is more successful than the others, and the duels do not match the Shaw Brothers' great successes. But still, the film is a lot of fun and offers great entertainment.
