A new family has moved in, and it's time for the block housewarming party to commence. As the party progresses, the children are introduced. First up is the eldest, Tom. Then comes the second eldest, Jean. Then comes the third child, and only daughter, Zoe. And everyone applauds...until it's revealed that the "third child" they thought they saw in the pretty pink dress was actually their youngest, a son named Ludovic.

...Yeah. Life for them becomes [[FromBadToWorse more difficult]] after that. See, Ludovic is not just a WholesomeCrossdresser, he's [[{{Transgender}} actually convinced he's really a girl]]. Even when confronted with irrefutable evidence, he figures it all out: When God was giving out all the chromosomes on the date of his conception, he accidentally lost a set of X chromosomes in the trash, and replaced them with a set of Y chromosomes. And while he's developing a sort-of crush on his new friend Jerome, the rest of the town is getting bent out of shape over whether or not they should let their kids hang around with a boy who habitually dresses in girl's clothes.

Comparable to the later ''Film/{{Tomboy}}''. Not to be confused with ''Film/LaVieEnRose''.
!!This movie contains examples of:

* AwkwardFatherSonBondingActivity: On the advice of his boss, Ludo's dad decides to spend more time with his son to get him to be more masculine, and enrolls him in football (soccer), encouraging him from the sidelines. Ludo is hopeless at the sport. After the game, the unbearably cruel locker-room taunting and gang-bullying will [[TruthInTelevision feel familiar]] to LGBT members of the audience.
* AmbiguouslyGay: Ludovic may or may not grow up to be gay. His (or her) parents are certainly worried he will, though.
* AmbiguousGender: It's hard to tell whether Ludo is transgender or just gender-variant, but the film seems to support the former more.
* BratsWithSlingshots: Chris has one and shoots Ludo with it as a way of saying hi. Ludo isn't amused.
* DisneyAcidSequence: Bizarrely enough. It involves a popular dress-up doll.
* DoubleStandard: In-universe one demonstrated in full at the end.
* DysfunctionalFamily: They're a harmonious and loving bunch at the beginning, but Ludovic's gender troubles cause all kinds of discord, to the point that [[spoiler: he says he wants to live with his grandmother instead of his parents and his parents let him and consider leaving him with her when they move.]]
* EverythingsBetterWithSparkles: Ludovic loves and wants to be like Pam, a Barbie-like doll and children's TV character. She tends to trail sparkles in the air around her. On one occasion Ludo imagines her blowing sparkly air that ties up two interfering mothers and takes Ludo, in a pink dress, and Jerome flying through the air with her.
* FairytaleWeddingDress: Ludo dreams of wearing one to marry Jerome.
* GiantPoofySleeves: Zoe's princess dress which Ludovic makes a grand entrance wearing.
* ImaginaryFriend: Ludovic's daydreams of being rescued by Barbie-woman Pam.
* MasculineGirlFeminineBoy: At the end of the film, Ludovic meets a boy named Chris -- short hair, shorts and T-shirt, catapult -- who turns out to be a girl named Christine. [[spoiler: During Chris's tenth birthday party she (or he, since he may be trans) makes Ludo swap costumes with her so that Chris is wearing the musketeer outfit and Ludovic the princess dress.]]
* MommasBoy: Ludovic has a good relationship with his dad but seems especially close to his mother, also to his grandmother and older sister. This, along with his parents' wish for a girl as their last child, is a possible explanation for his attraction to all things feminine. However as a sort of lynch-mob mentality develops among their neighbors--[[MamaBear threatening the family's livelihood]]--Mom can no longer tolerate Ludovic's gender nonconformity. She begins unpredictably lashing out, [[BerserkButton blaming (with shocking frankness)]] her child for their changing fortunes.
* OneOfTheBoys: We don't see much of Chris but as far as we can tell she/he pals around largely with boys.
* PimpedOutDress: Ludo loves them.
* {{Tomboy}}: Chris. Either that or she/he is a transboy.
* TransTribulations: Ludovic is misunderstood at every turn, tries to butch it up, fails, feels miserable, and attempts suicide. She gets better though.
* {{Transgender}}: Ludovic clearly feels transgender at seven. He/she may or may not grow up still feeling that way. Chris may be transgender as well.
* TruthInTelevision:
** Ludo's obsession with a Barbie-like character and love of pink dresses are realistic traits for a young transgirl or gender-variant boy.
** Likewise is her insisting that she's a girl.
** One might easily fail to grasp the full implications of [[InterruptedSuicide Ludovic's intent, after he's discovered in the giant freezer]] in the carport. (It wasn't just a hiding place.) More-recent first-time viewers of the DVD are more likely to "get it," assuming they've followed the news in the past couple of years.
* TraumaticHaircut: [[spoiler:Ludovic]] gets one near the end of the movie.
* YouthfulFreckles: Chris is freckle-faced.
