A fine tale of court intrigue centring around the old 'illegitimate heir' motif, with Lo Lieh as a wandering vagabond calling himself Swift Knight, who gets involved in the adventure Han Solo style. The script is more complicated than it needs to be, but Cheng Chang Ho handles it well whilst overseeing a slick production with great art direction and cinematography, and Lau Kar Wing provides some entertaining action choreography. Definitely a cut above average for the genre and year.
