Crosby plays a Philadelpia Quaker engaged to a Southern belle. He becomes a social outcast when he refuses to fight a duel. Fields then hires him to perform on his riverboat, promoting him as "Colonel Steel...the notorious Colonel Steel...the singing killer." The plot then follows a predictable course, but there are plenty of scenes featuring W.C. Fields.Crosby plays a Philadelpia Quaker engaged to a Southern belle.
