Zin is the Thai lover of Yakuza boss Masashi. Zin was previously the girlfriend of Thai gangster No. 8, who was jealous of her relationship with rival gangster Masashi. After Zin chooses Masashi, he forbids Zin from ever seeing Musashi again. Zin asks Masashi to go back to Japan, as they would not be able to be together safely. He begrudgingly leaves.
Soon after, Zin finds herself pregnant and moves into a new place to get away from No. 8. She has a daughter named Zen who is soon found to be autistic. As Zen gets older, Zin one day decides to tell Masashi about his daughter by writing him a letter. No. 8 finds out that Zin is in contact with Masashi and is furious. He visits Zin and cuts off one of her toes to remind her that she is forbidden from seeing Masashi.
Zin then falls ill with cancer and does not have the money to pay for chemotherapy treatments. Zen and Moom attempt to make the money needed to pay for the treatments.
This movie is an unexpected treat. A savant autistic martial arts master, excellent fight scenes, a variety of weapons, a good variety of fights, terrible dialogue and a story that was telegraphed from the first scene. Daddy, I am home. This is an 80s martial arts movie if I ever saw one. Pull up a chair gets some chinese food and enjoy…
