Evie Callahan is quality control assessor who doesn't like to take a lot of risks in her life. But after a relationship ends and her career hits a roadblock, she might be ready to change things up a bit.

Enter Xavier, a charming free spirit with whom she has an immediate spark. He lives a carefree life, which is a little different than Evie is used to. Along with encouraging her to seize the day, Xavier also believes the apocalypse is only eight months away.

He even has his own "apocalyst", a list everything he wants to do before the end of the world. He gets Evie to do the same, and with the help of her friends she must decide whether Xavier's claims have any merit while at the same time living her life more fully.
