Why Men Leave Home

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.
