Produced and distributed by Toei Company, it is a spin-off of The Street Fighter (1974),[1] and is the first entry in a trilogy of films starring Etsuko Shihomi as Kōryū Li.

On her way to Club Mandarin, she visits her uncle (Harry Kondo), who operates a restaurant, and her cousins Jerry (Tatsuya Nanjo) and Remi (Nami Tachibana).

Furious at his minions for failing him, Ryozo Hayashi (Shohei Yamamoto) hires a mercenary, Hammerhead (Milton Ishibashi), to spy on the shorinji kempo school, led by Tetsudo Fujita (Asao Uchida).

After Fanny reveals that Lee was captured, she gives Tina a necklace before spasming from a lack of exposure to heroin, which she had been forcefully addicted to, as Hammerhead's minions attack the ballet studio.

Hammerhead reveals the truth to Tina, that Lee is still alive and captive in Kaki's dungeon, before sending her off the bridge into an apparent watery grave.

Tina returns to Central Export and enters the dungeon, where she extracts Lee right before a sinister minister wielding an arrow gun offs him before her eyes.
