Poppy Cross is happy-go-lucky. At 30, she lives in Camden: cheeky, playful, frank, funny, and talkative to strangers. She's a conscientious and exuberant primary-school teacher, flatmates with her long-time friend Zoe, she's close to one sister and not so close to another. In this slice-of-life story, she takes driving lessons from Scott, a dour and tightly-wound instructor; takes classes in flamenco dance from a fiery Spaniard; encounters a tramp in the night; and sorts out a student's aggressive behavior with a social worker's help. Does her open attitude puts her at risk of misunderstanding or worse? What is the root of happiness?
