Poppy is a life-loving and irrepressibly cheerful primary school teacher. She is thirty years old, single, and infinitely optimistic and accepting. She lives with her best friend and flatmate Zoe in London. She is tested by a repressed driving instructor with anger problems, and, in turn, she decides to test him. She has exciting flamenco lessons, an encounter with a homeless man, an argument with her pregnant sister, and a love-affair with the social worker guiding one of her students. A joyously feel-good film.
