As Jen Guidry begins the process of choosing a school for her kindergartener, she celebrates all the opportunities that big-city life offers. Unfortunately for Jen, her husband has other ideas. He's ready to ditch the big-city headaches and move back to his hometown with a population of only 298 people. Jen finds herself along with her family (husband Mike, five-year-old Henry, and three-year-old James) trading in the bright lights of Dallas, Texas, for the lightning bugs of Graisseville, Louisiana. All Jen can think about is how far she'll have to drive to find a good cup of coffee.

The boys are ecstatic to be surrounded by trees and open spaces where they can just run. Mike is settling into his new role as owner of Big Ed's Parts 'n' More. Jen, however, has to make new friends and deal with all the eccentricities small-town life adds to her plate.

As Jen navigates the nuances and backstories everyone else in town takes for granted, she finds new friends and new adventures. She volunteers to coordinate the Live Nativity event at her church, finds a backup beauty queen, and organizes the annual Mardi Gras Parade. Jen finds she is living a life she never realized she was missing. Will she be able to completely give up the bright lights forever and appreciate her yard full of lightning bugs?
