Betty is an orphaned heiress living in Texas with her aunt and uncle. She falls in love with Bert, a flyer from Waco, but their plans to elope are thwarted by her uncle. When she is sent to New York City on her 20th birthday to be "properly introduced to society", she finds Bert, who is posing as her aunt's chauffeur. When a valuable pearl necklace that had been given to Betty is stolen that night, she and Bert set out to catch the thieves and prove to Betty's family that Bert is the kind of man Betty should marry.
