It has been 10 years since Abby Williams left home and scrubbed away all visible evidence of her small-town roots. Now working as an environmental lawyer in Chicago, she has a thriving career, a modern apartment, and her pick of meaningless one-night stands. But when a new case takes her back home to Barrens, Indiana, the life she painstakingly created starts to crack. Tasked with investigating Optimal Plastics, the town’s most high-profile company and economic heart, Abby begins to find strange connections to Barrens’s biggest scandal from more than a decade ago, involving the popular Kaycee Mitchell and her closest friends --- just before Kaycee disappeared for good.
