Mary Sundale is a member of a gay London set who call themselves "We Moderns" and scorns the Victorianism of her parents. They, in turn, have nothing but contempt for the ways of the younger generation. Mary is courted by John Ashler, a sane young civil engineer, but she fancies herself in love with a poetic humbug named Oscar Pleat ("God's Gift to Women"), a married man. In the course of a treasure hunt, Mary enters Pleat's rooms but is saved by John. However, she continues to associate with Pleat. During a jazz party aboard a zeppelin, Pleat tries to force his attentions on her; but Mary escapes after a plane crashes into the airship. Mary is glad to fall into John's arms and admits that her parents were right.
