Joan receives heavenly encouragement from God when she auditions for an overly ambitious director's school play about young zombies in love. In other developments, Kevin is leery of Andy's offer to drop the lawsuit; and Luke's bond with Glynis (Mageina Tovah) over science unleashes feelings of jealousy in Grace.

As Valentine's Day approaches, Joan worries that her romance with Adam could be sabotaged by his "perky blonde assistant" (Haylie Duff). Meanwhile, God tells Joan to familiarize herself with the poetry of the Romantic movement; Kevin keeps it a secret from Helen that he's going out with her ex-nun pal Lilly (Constance Zimmer); and Will debates whether to inform his wife of his problems with Lucy.
