This troubled production which took nearly three years to complete stars Tong Game of Death Lung as Lee Jun Kwong. His brother Jun Keung (Bruce Lee) was murdered whilst attending the funeral of a Japanese Sensei, Junku (Huong Cheng Li). Jung Kwong travels to Japan to investigate the mysterious murder. It's here the film reaches it's highes point, (accordind to my opinion) where he meets Louis (Roy Horan), a strange deerblood-drinking-rawmeat-eating American and close friend of the late Sensei. Jun Kwong's futher investigations reveal that Louis' martial arts fortress holds a deadly secret. 

The fights are of course good when Yuen Woo Ping choreographs them, but the saving of this movie is the character of Roy Horan, as the mysterious American. Just to add: the music in tthis movie is totally awesome!!!
