John and Irene Emerson's marriage begins well enough, but it is not long before John becomes less attentive. Feeling neglected, Irene spends more time with her girl friends, and John, consequently, falls prey to the vamping wiles of his secretary, Jean Ralston. When John comes home from the theater smelling of Jean's perfume, Irene procures a divorce; John then marries Jean. Grandma Sutton cleverly maneuvers John and Irene into her house and has it quarantined. They realize they love each other; John divorces Jean, remarries Irene, and takes her on a second honeymoon.
