In a fascinating departure from the austere moral drama in which he specialized, D.W Griffith demonstrates his talents for warm-hearted comedy in Sally of the Sawdust. W.C. Fields made his third screen appearance as Professor Eustace McGargle, a lovable confidence man who becomes the unlikely guardian of an orphaned circus waif (Carol Dempster).

Intending to return Sally to her grandparents, McGargle learns that her wealthy and esteemed grandfather (Erville Alderson) is a stern judge who harbors a deep contempt for shysters and shoe people. Faster than a sucker can say "three-card monte" McGargle finds himself wanted by the police and chased by bootleggers while trying to protect his cherished Sally, who has won the affection of a slumming socialite (Alfred Lunt).
