Miles Brewster Higgins, a self-conscious small town youth, endures his jealousy in silence when a flashy automobile salesman appears and captures the attention of his sweetheart, Irene Hayes. On the insistence of Cousin Roy, Miles invests in Baby Blue oil stock, which quickly earns a fortune. It is his intention to become engaged to Irene, then jilt her, but the rumor that his money was actually invested in another company -- and is therefore accruing no profit -- spoils his plans. Miles "faces the music" and learns that Grandma Brewster has spread the news about the false investment to test him. Miles has his fortune and his girl.
