Miss Potter is set in the high summer days of late Victorian and Edwardian England, during which Beatrix develops her natural skills as artist and story-teller. When she finally publishes her debut book, 'The Tale of Peter Rabbit,' she becomes a writing celebrity. It also leads to courtship and her first love with publisher Norman Warne, played by Ewan McGregor. Their relationship and his marriage proposal in July, 1905, was to change Beatrix's life for ever.
