The story of “Chocolate” takes place in Thailand, in which a local gangster, No. 8, finds out that his girlfriend Zin is in love with Masashi, a Yakuza boss. In order to stop them from seeing each other again, he cuts off his own toe as a symbolic gesture. To prevent further bloodshed, Masashi has no choice but to go back to Japan. In the meantime, Zin discovers that she’s pregnant and relocates herself so she can have the baby away from No.8.
While on the run, Zin gives birth to a daughter, Zen.
