薄暮時分，一個女孩走入鏡頭，俯瞰晚霞籠罩城市，鏡頭背後導演問女孩，「如果重新選擇，你會做什麼改變？」女孩用微弱的聲音說：「我想我再也不會選擇自殺這一條路。」Kathoey 一詞在泰文指把自己打扮為女生的男生，即一般認知的 Ladyboy，也是本片主角泰（Tay）的性向。當外界對泰國的想像是性別自由相對包容時，泰卻因為個人性向的選擇，在校園裡遭人公然羞辱、傷害，導致他企圖自殺。影片專訪一位跨性別老師，聽其親身經歷，從社會目光到職涯發展侷限，釐清跨性別者在泰國的實質處境；也採訪泰的同學和母親。鏡頭避開暴力言語，期許以寬厚精神體貼每顆心靈，如泰所言，我們在花火中為世界賦予不一樣的顏色。

The teenaged Tay is a ladyboy, or "kathoey," as members of this relatively well-tolerated transgender group are called in Thailand. These are people who take on a traditional female role, and some describe them as a third sex. The documentary starts with Tay looking out over the twilit city. Offscreen, the filmmaker asks him a question: “Do you think you made a mistake now that you are in the media?” Tay answers, “I kind of do.” The voice then asks,  “If you could go back in time, what would you have changed or fixed?” Tay replies, “I would not try to kill myself again.” Interviews with sympathetic fellow students and a teacher who is also a kathoey demonstrate the level of acceptance for his sexual orientation at his Christian school Saint Joseph Mueang-Ake. This becomes most triumphantly clear when Tay appears at a school Christmas party in a beautiful red dress. But as his tearful mother explains, one single intolerant and violent teacher drove him to attempt suicide. Elsewhere in the film, we see Tay going about his daily life, traveling to and from school, and silently touching up his makeup in front of the mirror.
