青春在生活的侗偬间稍然撤离，面对世界的热情与理想还留下多少？
「快乐是失望的累积？」茱莉因感情破灭自杀，刚刚出院；阿里从摩洛哥到法求学，深刻体验种族歧视的真实处境。
爱蜜莉和男友濒临分手边际；卢卡斯在枯竭的生活中试著发现真我。赛西儿最不缺乏的就是时间，藉著摄影摆脱无聊；尚一保罗则是狂热虔敬的天主教，寻求自我的信仰实现。
六个人，朋友，六段生活，想找出自己的人生方向，为此奋战与挫败。但在寻求的过程中，也迸现著感动交织的闪光片刻，属于同一世代共享，近乎秘密的——沉溺爱情，不期而遇，或心灵相通的，快乐。

Yann Kerbec is a flight instructor: he evaluates pilots’ abilities under extreme conditions on flight simulators. But Yann has a big problem: he is so airsick since he was born in a plane, that he couldn’t even follow the love of his life when she moved to Australia. Yann is now thirty years old and remembers with both nostalgia and humour the numerous love stories he spoiled because of his phobia. Will he finally accept to become a grown up or will he keep making plans in the air?
