Marin County, California, summer, 1979. When young women start turning up dead on the mountain behind the home of Rachel and her devoted eleven-year-old sister, Patty, their father-a larger-than-life, irresistibly handsome (and chronically unfaithful) detective-is put in charge of finding the "Sunset Strangler." Watching her father's life slowly unravel as months pass and more women are killed, Rachel embarks on a dangerous game to catch the killer. Her actions will destroy her father's career and alter forever the lives of everyone she loves. Thirty years later, believing that the wrong man was arrested for the crimes, leaving the true killer at large, Rachel constructs a new strategy to smoke out the Sunset Strangler and vindicate her father-and discovers more than she bargained for.

Loosely inspired by the Trailside Killer case, After Her is part thriller, part love story-a poignant, suspenseful, and painfully real family saga that traces a young girl's first sexual explorations, the loss of innocence, the bond shared by sisters, and the tender but damaged relationship between a girl and her father that endures even beyond the grave.
