Passing herself off as a countess, glamorous Lucy Stavrin hobnobs with the rich and famous along the French Riviera. Aware that Lucy is a phony, jewel-thief Malatroff blackmails Lucy into helping him steal the valuable necklace owned by the young wife of phlegmatic American businessman Sylvester Corbett.
Unfortunately the movie Slightly Scarlet is not yet available on HBO Max.
