We will wash away your pain and iron away any creases in your heart. Overnight, in the village of Marigold on top of a hill, old Jieun has conjured up a magical Mind Laundry, where she cleanses painful experiences from her customer's hearts, transferring them into stains on a T-shirt and transforming them into dazzling red petals. We meet five of Jieun's customers to her laundry: a frustrated young filmmaker; a tortured social-media influencer; a distraught mother who has discovered her husband’s other family; a young woman two-timed by her lover, and Yeonghui, a victim of bullying, who works as a delivery man to escape his pain in routine.
