A young autistic woman named Zen has developed uncanny martial arts skills by copying what she sees on television, as well as at the Muay Thai academy next to her home. She also has uncanny reflexes and is able to catch balls thrown at her without even looking.

Zen is the daughter of Zin, the Thai wife 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 shoots his own toe and forbids Zin from ever seeing him 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.
