Archduke Alexander (Clive Brook) is better known for his sexual conquests than his diplomatic triumphs. After a lifetime of loving 'em and leaving 'em, the Archduke finally meets a girl he can't leave, Hungarian lass Judith Peredy (Billie Dove). She resists his advances but can't hide the fact that she's in love with him. The Yellow Lily was the second of four cinematic collaborations between star Billie Dove and director Alexander Korda.
