With the knowledge of death dates available to the world, Corrie knows that she will die before she turns 20. Living in a society that oppresses those who will die young, Corrie tries to use her leadership role in her labor camp for "short-lived" to secretly create change. But after learning that her best friend doesn’t have a death date and therefore can’t die, she begins to question the system even more. Seeking answers, Corrie connects with the source of the death dates and discovers not only that her death date is three days away, but that she also has a family outside the Prime. Facing a new desire for answers, Corrie escapes to an outside world she has never seen before to find her family and the truth about the death dates.
