Sam Bisbee (W. C. Fields) is an optometrist and an amateur inventor. His daughter Pauline (Joan Marsh) is in love with Bob Murchison (Buster Crabbe), but Bob's upper-class mother (Kathleen Howard) wants nothing to do with anyone related to uncouth Sam Bisbee. Even Sam's wife Bessie (Louise Carter) is ashamed of him, because he prefers to be himself rather than put on airs. Pauline is the one woman who truly loves Sam, accepting her father as he is.
