Miss Moffat is a strong-willed Welsh schoolteacher working in a small poverty-stricken coal mining town. Under her guidance, an illiterate teenager, Morgan Evans, transforms from bully to brilliant student.

Kate Burton joins the ranks of Ethel Barrymore (original production on Broadway), Bette Davis (in the film version), Katherine Hepburn (in the made-for-TV movie), and Cicely Tyson (in the Broadway revival) in the distinguished lineage of actresses who have played Miss Moffat. Miss Burton's son, Morgan Ritchie, plays the role of Morgan Evans. Nicholas Martin directs.
