It's sports day and a seventeen-year-old boy prepares to compete, as he has many times before. Only this time it's different, his childhood is behind him, different feelings, emotions and desires engulf him as he watches his classmates. His life is about to change.

少年圣塞巴斯蒂安异常俊美，高卢国王爱上了这个近卫队长，甚至愿意拿一半江山来得到他的爱。但塞巴斯蒂安是一个虔诚的基督徒，他宁可被乱箭射死也不肯从命，最终以殉教结束了自己的生命。据说这便是 1月20日圣塞巴斯蒂安节的由来。 本片取自圣塞巴斯蒂安的故事，该故事是西方绘画和雕塑艺术的重要题材。而导演巴沃·德弗恩赋予这个故事以隐藏的少年情愫，暗示圣塞巴斯蒂安不肯从命是因为他有一个秘密爱人， 从而让电影拥有更曲折的情怀。电影使用了大量仿古镜头和默片格式，画面超脱世俗的清新唯美。
