The consciousness of each "special child" has a unique ability or skill inside since birth. It is called a "gift". A special child like "Zen" (Jeeja Yanin), whose mother "Sin" (Som Amara) is in the final stages of leukemia, could never have known that trying to exercise the rights of her mother will lead her mother and herself into an unknown world. Because her mother used to be an important woman of Number-8 (Off Pongpat), the leader of the most powerful and terrifying Mafia gang in Thailand.
Consequently, her journey is a key factor leading to the confrontation between Number-8, of the Thai Mafia gang, and Masashi (Hiroshi Abe), a key member of Japanese Yakuza, who tries to protect Zen and her mother. It seems that the only way Zen has is to use her fighting gift to protect her mother.
