Grandmother Mi Ja (Yoon Jeong Hee) works part-time as a caretaker, and struggles to raise a teen grandson (David Lee, Paradise Murdered) by herself. Despite her tough situation, she speaks softly, dresses fashionably, and approaches the world with child-like curiosity. Enrolling in a poetry class, she endeavors to capture life in verse form, but her simple dream of completing a poem is stalled by the early signs of Alzheimer's disease and the heavy financial and emotional burden of her grandson's shocking wrongdoing.
