In Camden, the elementary school teacher, Poppy Cross, is a very optimistic thirty year-old smiler that has been sharing a flat with her friend and co-teacher, Zoe, for ten years. When her bicycle is stolen, Poppy decides to have driving lessons with the Axle School of Motoring with the rude, bigoted and bitter instructor, Scott. Meanwhile she has trouble with her back after having a go on the trampoline and decides instead to take Flamenco classes with a Spanish teacher. When her pupil, Nick, bullies other students, Poppy feels that the boy is having troubles at home. She asks for the assistance of the social worker, Tim, and they start to date each other. However her attitude of happiness and joy is misinterpreted by Scott.
