Ronald Brooke, an English exchange professor at a Midwestern college, is astounded at waitress Jenny Swanson, whose ambition is to gold-dig her way to Paris. Jenny begins to realize her dream when Ted Dayton, the son of a millionaire, hits her with his car and she entices him into a marriage proposal. When her conscience prevents her from going through with a breach of promise suit, Ronnie counsels her that good girls go to Paris too, and then informs her that he is leaving town to marry Sylvia Brand. Jenny, under orders from Mr. Dayton, must leave town also, and en route to New York, she meets Tom Brand, the spendthrift grandson of millionaire Olaf Brand and brother of Sylvia. Upon reaching New York, Tom and Jenny go nightclubbing, where Jenny learns that Sylvia is in love with Dennis Jeffers, the butler's son, but fears that her grandfather will disinherit her if they marry. That night, Tom becomes so drunk that Jenny takes him home to the Brand mansion, where she meets Tom's mother Caroline, who introduces Jenny to the irascible Olaf as Sylvia's roommate. Olaf welcomes Jenny into the house when she prescribes old Swedish remedies for his imagined ills, and soon she gets Tom out of a jam involving a gambling debt. She also ruins the plans of gigolo Paul Kingston, who intends to attach himself to the Brand millions by romancing Caroline. After Jenny prods Sylvia into admitting her love for Dennis, Ronnie proposes to Jenny, promising her a honeymoon in Paris.
