The Honeymoon Express (1926)

Wealth turns some of the Lamberts down the path of decadence and dissipation: John, the promiscuous father, gets entangled with gold-digger Estelle; his architect son Lance loses ground in his profession through drinking; and reckless flapper daughter Becky 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 Jim's brother Dick; and the family is united with Jim at its head.
