Evie is a risk-averse quality-control assessor, who appreciates order. Then Evie meets charming, free-spirited Xavier, who encourages Evie to carpe that diem, because he believes humankind has a mere eight months and twelve days until a runaway asteroid smacks us all into stardust. That's why he 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, Evie must decide whether Xavier is certifiable and whether that even matters, if being with him means living her life more fully. Corinne Brinkerhoff, Scott McCabe and Tori Stanton wrote the episode.
