A young girl is caught up in the 1980 Gwangju massacre, where Korean soldiers killed hundreds, if not thousands, of protesters who opposed the country's takeover by the military the year before. Flashbacks show the girl seeing her mother shot to death in the massacre. The film spurred the Korean public to demand the truth behind the incident, and their government eventually opened previously classified files on the massacre. 《花瓣》及其背景。张善宇总是让小孩做大人的事。政权与人民。在枪炮强权面前凋落的花瓣。 精神错乱的15岁少女任人欺凌，背后隐藏着不为人知的悲惨身世,经过江边的张，发现一15岁少女目不转睛望着他，进而将他认作是哥哥而紧跟在后，起初他只觉少女精神异常而任意的欺凌，随着时日，渐渐发现常保沉默而显自闭的少女原来有个非常痛苦的一段过去…… 影片根据作家崔尹的小说改编，以韩国光州5.18时期为时代背景。谈到创作意图，导演张善宇说：“故事最吸引我的地方就是1980年5月的光州。当时建立了很多拘禁违反戒严令‘犯人’的监狱。街头活报剧运动也十分活跃。这样一个特殊的时期应该用一部电影来呈现。”
