在这部未来惊悚片，世界成为一片冰冻的荒芜之地。残存的人类居住在一列巨型列车上，永无止尽地绕行全球。

劳拉（拉娜·孔多尔LanaCondor饰）是一个16岁的女孩，无论是外貌还是性格，劳拉都只能算是最普通的那一挂，把她扔在人堆里，下一秒钟你就绝对再也无法注意到她。然而，劳拉的心思细腻情感丰富，让她特别容易对男孩产生好感，但她总是将这份爱慕隐藏在心底，只是通过写信的方式来抒情，一段时间下来，劳拉积攒了不少的情书，她将这些情书藏了起来，并决定将它们当做自己永远的秘密。可让劳拉没有想到的是，自己的这些私房信竟然在某一天被统统公之于众。信件带来的巨大反响很快就令她的生活发生了天翻地覆的改变，面对各方的声音，无论是嘲讽和还是善意的，勇敢的劳拉都以一颗平常心面对。
