In first grade, twins Alexis and Adam wrote down what they wanted to be when they grew up and put it in their teacher’s time capsule.
Now entering their senior year in high school, they are surprised to find out what they wrote: Alexis wanted to “help people” and Adam wanted to be a fireman.
But that was before Adam got sick and their family fell apart. Adam’s leukemia is now in remission but, sadly, so is the twins’ family.
Their mother and father are always working—not only don’t they have time for Alexis and Adam, they don’t have time for each other.
Alexis can’t even convince them to take a weekend off for one last family vacation to Disney World.

一年級的時候，雙胞胎兄弟亞歷西斯和亞當寫下他們長大後的志向，並放進老師的時空膠囊中。

現在他們即將升上高年級，看到當年所寫的東西，兩人都相當驚訝：亞歷西斯想要「熱心助人」，而亞當想要當個消防隊員，但這一切都是亞當生病，以及家庭發生變故前的事了。亞當的白血病進入緩解期，但不幸的是，家人間的感情也逐漸冷淡。

他們的父母總是忙於工作，不只沒有時間陪伴小孩，夫妻倆也沒有獨處的時間。

亞歷西斯無法說服他們安排一個周末的休假時間，全家一起去迪士尼樂園玩。
