Fifty years after winning the Pulitzer Prize, To Kill a Mockingbird remains a beloved bestseller and quite possibly the most influential American novel of the 20th Century. Behind it all was a young Southern girl named Nelle Harper Lee, who once said that she wanted to be South Alabama's Jane Austen. Hey, Boo explores Lee's life and unravels some of the mysteries surrounding her, including why she never published again. Containing never-before-seen photos, letters and an exclusive interview with Lee's sister, Alice Finch Lee, the film also brings to light the context and history of the novel's Deep South setting and the social changes it inspired after publication.
