The first of Nancy Carroll's talkie films for Paramount had already been released when Fox's silent Sin Sister was taken off the shelf. Carroll is cast as Pearl, a vaudeville dancer stranded somewhere in Alaska. With no local Equity office in the vicinity, Pearl is obliged to accept the hospitality of a wealthy family which has itself been stranded in the Great White North. An ill-tempered fur trader and a looney Eskimo both lust after Pearl, but she is rescued by Peter Van Dykeman (Lawrence Gray), her hosts' male secretary. Despite the presence of four screenwriters in the credits, it would seem as if Sin Sister was made up as it went along.
