When her dream internship with an independent record label in Los Angeles falls through at the last minute, Cassie, a college student in the Music program, reluctantly returns to her home town of Apple Springs, Washington for the summer break, she who will be house-sitting at her parents’ while they go off on vacation to France. Instead of working at the diner with her best friend Lucy like she did when she was in high school, Cassie, who loves children, manages to find a part-time nanny job looking after pre-schooler Becca Paine, as her mother, Chloe Paine, is planning on returning to work part-time as a lawyer. Cassie and Lucy’s return to town coincides with a woman named Mallory Raymond having gone missing, she the wife of Glenn Raymond, who works in construction for Becca’s father/Chloe’s husband, Tom Paine, the owner of his own park design company. Sheriff Hayes sat on the case in believing Mallory ran off as Glenn has been open that they were separated, but now, from new material evidence, places Glenn at the top of the suspect list in Mallory’s disappearance. Shortly thereafter, another wife in town goes missing as more and more suspicious activity occurs within Cassie’s midst as she goes about her job. Refusing to abandon Becca, Cassie stays with the job even in light of information that her own life might be at risk staying at the Paine home.
