Wealth turns certain of the Lamberts to decadence and dissipation: John, the promiscuous father, gets entangled with a gold digger named Estelle; his son Lance, an architect, loses ground in his profession through drinking; and Becky, the reckless flapper daughter, is infatuated with Nathan Peck, a vitiated millionaire. Margaret, the mother, who has lost her beauty through devotion to her household, realizes the futility of the sacrifice and leaves home with Mary, her youngest and unspoiled daughter, whose aversion to men is expressed in her mannish attire. Margaret becomes an interior decorator in Jim Donaldson's office and soon regains her dignified womanly beauty. Meanwhile, Lance denounces his father for inviting disreputable people home and gets a job through his mother's influence. Margaret refuses John's pleas to return, and with Jim she saves Becky from suicide; Mary falls under the charms of Dick, Jim's brother; and the family is united again with Jim at its head.
