Thirty years old and single, Pauline "Poppy" Cross shares a London flat with her best friend Zoe, a fellow teacher. Poppy is free-minded, high-spirited and kind-hearted. The film opens with Poppy trying to engage a shop employee in conversation. He ignores her, yet his icy demeanour does not bother her. She maintains her good mood even when she discovers her bicycle has been stolen. Her main concern is not getting a new one or finding the bicycle, but that she did not get a chance to say goodbye to it. This prompts her to decide to learn how to drive.
