Party Husband finds ex-Ziegfield Girl Dorothy playing the better half of a thoroughly “modern marriage” whose openness threatens to bring about its premature end. Fellow Ziegfield alum Mary Doran plays the coquette whose intended conquest of the free-thinking hubby (James Rennie) starts to throw the couple’s “understanding” awry.
