[1] As summarized in a film publication,[2] a prologue, which explains where the author got her idea for the story, shows Adam and Eve in the Garden of Eden.

Shifting to the modern story, Mrs. Orrin (Effie Shannon), Eve's (Constance Talmadge) mother, goes into hysterics at the thought of losing her daughter.

Fearing her mother's nerves, Eve is willing to marry Henry, so the four of them go to Mama Orrin's birthplace, where the wedding is scheduled to take place on her birthday.
