[[caption-width-right:337:Unfortunately, this is one conflict that isn't gonna be solved with diplomacy.]]

A 2008 Thai film about an autistic girl who goes after her ailing mother's debtors to pay for her chemotherapy.

A Thai woman falls in love with a Japanese gangster, but they part ways after her employers disapprove... with violence. A few months after the split, she gives birth to Zen, a girl with autism. Said autism allows Zen to master martial arts moves by watching them. She also enjoys chocolate, [[TrivialTitle thus the title.]]

When Zen's in her teenage years, her mother gets cancer and needs money for treatment. Zen's friend (and occasional caretaker) Moom finds a black book listing everyone who owed her mother money from her days as an enforcer. They head out to reclaim it... with violence.

Unfortunately, those people are with the same criminals that split up Zen's parents, and they're still hungry for revenge...

(For the 2000 film about a chocolaterie in a French village, see ''Film/{{Chocolat}}''.)

!!This movie provides examples of:

* ActionGirl: Zen. Zin was a DarkActionGirl in the backstory, or possibly a DragonLady.
* AgonyOfTheFeet: During Zin's acrimonious departure at the start of the film, her boss shoots his own big toe off to show Zin just what she's done to him. [[spoiler:He later cuts one of Zin's toes off when he finds out she's still contacting her yakuza boyfriend.]]
* AmbiguousDisorder: Zen's disorder is never named, but it's pretty clearly a form of autism. Thomas's disorder looks like full body Tourette's, but that doesn't explain all his symptoms.
* AntiHero: Zen and Moom have a good cause... but they're basically collecting money owed to the mob for their own personal use.
* BadassFamily: Dad's a (very good) gangster. Mom... had moves before the cancer. Their kid is unstoppable.
* BigDamnHeroes: A few examples. The most hilarious (and overt) being Moom saving the day by... scaring away the flies using an electric flyswatter, thus allowing Zen to mop the floor with the people she's extorting money from.
* BittersweetEnding: [[spoiler:Zen's mother is killed by the BigBad. However, by this point, Zen has defeated everyone who stood against them... so her father doesn't have to leave again, and she is reunited with him.]]
* TheBladeAlwaysLandsPointyEndIn: Played straight many times in the butcher shop fight, but notably subverted at one point. Zen deflects a thrown knife at a mook who was already victim to this trope. You see his face and reaction when he's hit... then the camera pans downward and it turns out it merely slapped him with the side of the blade.
** Earlier in the same fight, the blade ''didn't'' land pointy end in on a chain link barricade, but did when it [[ThrowingYourSwordAlwaysWorks bounced off and hit the mook who threw it...]]
* ChekhovsGun: "Flies!"
* CombatParkour: Zen, a small Thai autistic girl whose DisabilitySuperpower is to absorb martial arts from movies and TV shows. The entire movie is her beating up hundreds of people larger than her with Muay Thai. The actress supposedly spent 2 years learning enough Muay Thai to make it look realistic. The film handled her smaller size well - she uses it to her advantage by taking the fight into narrow spaces where her opponents have trouble moving. She and her opponents also employ Combat Parkour in places when evading kicks and bouncing around the scenes.
* ConfusionFu: Zen's most dangerous enemy is Thomas, a boy with Tourette's. Not only he is skilled, his tics make it almost impossible for her to read his moves.
* ConservationOfNinjutsu: Zen goes through {{mooks}} like it's nothing, but has some difficulty with Thomas.
* CursedWithAwesome: Autism, as well as Tourette's apparently.
* CuteBruiser: Zen of course.
* DanceBattler: Not easy to call "dance" to Thomas's spastic fighting style, but he actually fights with an adapted form of UsefulNotes/{{Capoeira}}.
* DisabilitySuperpower: Zen is autistic... which gives her almost superhuman senses. Same for Thomas, who has some sort of Tourette which makes him physically unpredictable.
* DisneyAcidSequence: The film features an [[DreamBallet animated dream sequence]] which moves Zen to act.
* DoubleKnockout: Zen and Thomas feature one at the final moments of the fight when they both try and land a ''martelo do chao'' at once.
* TheDragon: Thomas.
* EvilCounterpart: Thomas counts as one to Zen.
* GoodOldFisticuffs: Zen uses them frequently.
* HilariousOuttakes: A weird breed, as they're actually footage of on-set injuries.
* IKnowMortalKombat: Zen primarily learns martial arts watching Creator/BruceLee and Creator/TonyJaa movies. Apparently including training videos, like in the clip that shows her absorbing every movement. Additionally there is a muay thai class training near her house that she seems to audit without their knowledge.
* ImportantHaircut: Zen cuts off her beautiful long hair after she finds out her mother is going bald from chemotherapy. [[spoiler:She had pulled off her mother's wig and, in a series of flashbacks to times she'd played with her mother's hair, thought she'd torn off her mom's real hair. She was apparently acting out because of the trauma.]]
* InformedAbility: Thomas is credited as the "Epileptic Boxer", which is quite misguided considering he is neither a boxer nor exactly epileptic.
* ItsNotYouItsMyEnemies: The reason Zen's parents aren't together. If they so much as communicate in a letter, it angers the BigBad.
* KickTheDog: Number Eight [[spoiler:on Zen, ''in her face'', as she tries to revive her mortally-wounded mother.]]
* KungFuProofMook: A literal example in Thomas, who proves to be a match for Zen. Even after she finds the way to land some hard strikes on her twisty antagonist, he manages to pull a draw and takes her out of action (although, to be fair, she was already worn due to an earlier fight against bunch of mooks).
* LittleMissBadass / BadassAdorable
* LoanShark: Zen and Moom, are, effectively, acting as enforcers for the mob's loans and keeping the money.
* MalignedMixedMarriage: Less because it's a marriage between a Japanese man and a Thai woman, more because it's between a yakuza and a Thai Enforcer.
* MartialArtsMovie: Duh.
* MixedAncestry: See above.
* NiceJobBreakingItHero: Zen and Moom collecting debts is essentially stealing from the mob, which puts them back on Number Eight's radar.
* NonActionGuy: Moom qualifies, while he occasionally contributes in fight scenes, for the most part he simply keeps out of Zen's way.
* NonIndicativeTitle: Zen does enjoy chocolate, and it shows up in several scenes, however it's never a plot point and a very random choice for a title.
* OneWordTitle: It's named ''Chocolate'' because the main character likes the stuff.
* PacManFever: Zen's playing a [=PS2=] with a Super Famicom controller at one point.
* PowerCopying: Zen shows it (with a lot of effort, due to her opponent's body language being difficult to read) during her battle against Thomas. She soon adopts some capoeira approach to match his style and manages to finish him with a ''mariposa'' kick while dodging a sweep.
* QuirkyMinibossSquad: The Thai mob seems to employ a QMS of transvestites.
* RealityEnsues: Played straight, then subverted. Mooks swarm into the room with katanas drawn, and it looks like it's going to be an epic sword fight between them and Zen's father, until [[spoiler:[[CombatPragmatist he pulls a gun and empties into their ranks]].]] For the subversion, he grabs a blade of his own and fights the rest traditionally.
* RealityIsUnrealistic: Zen's WaifFu moves look like they shouldn't pack that much weight... until you see the HilariousOuttakes and you see that when her blows hit the stuntmen, they do some serious damage.
* SweetTooth: Zen, it's why the movie is named what it's named.
* TrademarkFavoriteFood: Zen loves chocolate. At one point the gangsters [[{{Squick}} use it against her]].
* TrivialTitle: The movie is about an autistic girl beating people up to pay for her mother's chemotherapy. She also happens to like chocolate, though that doesn't affect the plot in the slightest aside from drama.
* WaifFu: Done well for the most part. Zen has to build up momentum be able to knock back her opponents more than a few inches. See RealityIsUnrealistic.
* WhatHappenedToTheMouse: Moom in the very final scene, especially since he was [[spoiler:pretty badly wounded]]. Also, Thomas's fate is unrevealed.
* WhyDidItHaveToBeSnakes: Zen ''hates'' flies.
* {{Yakuza}}: Zen's dad Masashi.
