For over 50 years, Coronation Street has reflected society's changing attitudes, and has never been afraid to tackle taboo subjects. In the first of a new six-part series, stories include Leanne Battersby's scandalous days as an escort, how two famous barmaids at the Rovers Return Inn both hid similar secrets, and John Stape's affair with schoolgirl Rosie Webster. Narrated by Katherine Kelly, including interviews with cast members Julie Goodyear, Jane Danson and Nigel Havers.
