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.

No one is prepared when Adam gets sick again, but this time Alexis is not alone. Adam's illness reunites the family. And Alexis discovers that the time capsule predictions weren't so far off the mark.
