The movie starts with Don Wong discussing military strategy with a general but he is really there to assassinate him. Cut to the other military men decide to get the assassin before they start their campaign. A masked person also suggests to get the man who ordered the assassination. Don delivers the head then plans to escape to Taiwan. Next John Liu enters the story as a mystery man of martial arts. He observes a bare breasted woman cheating at the casino and follows her to demand a share of the loot. Don cuts in. After a chat with her he returns to a trap. He is worn down and injured in the ensuing fights but John comes to the rescue. It results in John escaping and the girl taking Don to a cave to heal his wounds. Fortunately for Don the girl's bare breasts are an antipyretic. On recovery, John arrives to challenge Don to a future fight.
No credits can be found for this female actor. In the casino she appears to do a topless scene but it could have been a double. The snake tattoo on her chest does not perfectly match and the breasts and face are not shown together. So perhaps there are two women of mystery in this movie.
Speaking of details also pay attention to the final fight. Don really kicks the guy in the head with a full power flying side kick. There was no need for take number two in that fight sequence. John and Don made a great martial arts pair in their movies together. Don had a chance on Hollywood with his 1978 "Tiger Man". The movie was made to fit the mold of what Hollywood called a martial arts movie and it failed because Hollywood had no idea of what a martial arts movie should be. John, on the other hand, decided to produce his own films and the results proved he was really in the movie business to score some women.
Overall I rate this movie as just a bit above average for the year and genre. That comes as a bit of a disappointment though. In 1976 John and Don and Hwang Jang Lee made "Secret Rivals". "Secret Rivals" was a movie that stood out as completely special from every martial arts movie up until then and it was all because of the amazing high kicks. Here it is just three years later and those amazing high kicks have become just a bit better than average.
