Two strangers—a man (played by Bruce Li) and a woman—appear on the White Wolf Hills, where a powerful crime boss and his lackeys have their headquarters. Naturally, the gang are suspicious and try to turn the interlopers away, but they are no match for the pair, who prove to be extremely talented fighters. Concerned that the uninvited visitors are after the stolen King's seal currently in his possession, the crime boss hires skilled martial artists to help take care of business. Meanwhile, a seemingly friendly restaurant owner (Poon Chuen-Ling) tries to help the strangers, but in reality he is a treacherous thief out to make himself rich.
Is it possible for a martial arts flick to have too much action? I never really thought so until I saw Dragon Warrior (as the UK DVD release of Duel In The Tiger's Den is known), which consists of one fight sequence after another, with very little else of note to get in the way of the frantic kicking and punching. While this might sound like a chop socky fan's idea of heaven, it actually grows surprisingly dull after a while. If there had been a bit more variation in the pacing and a touch more focus on a stronger narrative (the plot becomes very muddled at times), Dragon Warrior could have been an extremely enjoyable old school martial arts flick; instead, it is merely a mildly entertaining but instantly forgettable time waster.
