When an abrupt divorce turns her world upside down, Martha finds herself leaving a decade-long relationship and learning how to navigate the world as a 33-year-old single woman. She thinks she can hide from the pain by diving into her job, spying on adulterous spouses like her own and busting them.
But when musician Thomas Remmy approaches her regarding his sister, who has been missing for ten years, Martha finds herself taking on a purpose bigger than cheaters and marital problems: She and her best friend, Daisy, have a chance to bring home Chloe and Sydney, both who vanished within a year of each other. A chance to heal two families and find out the truth of what happened to these lost girls. A chance for Martha to make her career more worthwhile, and to find the new version of herself in the pieces of who she used to be.
