Evie Callahan (Tori Anderson) appreciates order. Whenever she's making a list, "make a list" is both the first thing on it and the first thing crossed off. Such a regimented life has its drawbacks. Her on-again/off-again romance with the sweet, but soft-spoken Timothy (Jesse Rath) has sputtered out, and her boss, Deirdre (Amy Pietz), a petty tyrant with breath that could kill a plant, laughs off her career ambitions. Then Evie meets charming, free-spirited Xavier Holliday (Joshua Sasse), and the attraction is immediate and electric. Xavier brings a jolt of joyful, rollicking romance into her life. Xavier encourages Evie to carpe that diem, because it’s more fun that way and also because, he says the apocalypse is, you know, nigh. He believes humankind has a mere eight months and twelve days until a runaway asteroid smacks us all into stardust. That's why Xavier made an Apocalyst - a tally of every last thing he wants to do before the world goes kaput. So with the help of her friends – Hank (Jonathan Langdon), a diehard conspiracy theorist, and Kareema (Sarayu Blue), a droll nihilist – Evie must decide whether Xavier is certifiable and whether that even matters, if being with him means living her life more fully.
