An unfaithful husband and his daughter go on nightly club outings, leaving the mother at home. The mother rebels against her lonesome life and attempts to prevent a man from pursuing her daughter.

Gregory La Cava directs this comedy of errors, starring W.C. Fields as a hen-pecked, inebriated inventor who triumphantly creates unbreakable windshield glass while struggling to gain the respect of his social-climbing daughter and nagging wife.
