When Mary Graham's old school chum visits, Mary's husband becomes infatuated with his wife's guest and soon openly avows his love for her. Mary is powerless to stop the affair and confides to old friend James Livingston the expected arrival of their child. Hiding her pregnancy from her husband, Mary goes to the country, where her son is born. Learning that Robert is intent upon filing for divorce, Livingston demands that the unfaithful husband repay some notes which Livingston holds. Robert is unable to pay, and Helen threatens to leave him. In contrast, Mary offers to sell her jewels to help her husband, forcing Robert to realize her true worth. He begs his wife's forgiveness, and they are joyfully united as Mary proudly introduces her husband to their son.—Pamela Short
