Paris, 1974. Radha is now living in Paris with her husband, Pierre, and their two daughters. She still grieves for the baby boy she gave up years ago, when she was only a child herself, but she loves being a mother to her daughters, and she's finally found her passion, the treasure trove of scents. She has an exciting and challenging position working for a master perfumer, helping to design completely new fragrances for clients and building her career one scent at a time. She only wishes Pierre could understand her need to work. She feels his frustration, but she can't give up this thing that drives her. Tasked with her first major project, Radha travels to India, where she enlists the help of her sister, Lakshmi, and the courtesans of Agra, women who use the power of fragrance to seduce, tease and entice. She's on the cusp of a breakthrough when she finds out the son she never told her husband about is heading to Paris to find her, upending her carefully managed world and threatening to destroy a vulnerable marriage.
