Marilyn Parker (Linda Watkins, a young unsophisticated wife, who while her husband, Rex Parker (Alan Dinehart), is in Europe on "business" but took his mistress, Peggy Burns (Greta Nissen), with him, sub-leases his former "love nest" and becomes friendly with the gold-digging blondes and their 'daddys' that Rex and Peggy formerly entertained. She meets Boyce Cameron (John Boles), a wealthy bachelor and they fall in love with each other.
The Haddocks are going on a European vacation and from their reception at the station, where the whole town goes to see them off, it is clear who wears the pants in the family - it's their daughter Mildred. Her parents often proclaim she is a genius - but she is just smarter than them, which wouldn't be too hard! On the train, Finn meets shyster Harry who sizes Finn up as a sucker and quickly wires his partner Bessie, aka "The Princess" to make Finn's acquaintance and take him for everything he has.
