Margaret Holt and her brother Victor set out to smash a narcotics ring responsible for their father's death. Young reporter John Howell and eccentric mystery writer Winthrop Clavering help unravel the truth about the murder.
Mae Murray plays a willful American lass whose wealthy dad (Robert Edeson) sends her to Paris so that she may pick up some "refinement." Instead, she picks up a fortune-hunting nobleman, played as a frivolous fop by a monocled Andre Beranger. True-blue hero Conway Tearle prevents Murray from making a bigger fool of herself than she already is.
