Jerry Benham, the ten-year-old heir to a vast fortune, must remain on the Benham estate, where he has no contact with any female, until his twenty-first birthday, according to the will. Ten years later, while fishing, Jerry meets beautiful Una Habberton, who has wandered through a broken gate onto the estate. She returns many times to their "Paradise Garden," and an affection grows between them. However, when Jerry's kindly guardian, Roger Canby, finds them together, he sends Una away. Upon reaching twenty-one, Jerry, curious to see New York, goes there with another mentor, Jack Ballard, and is introduced to the business and society life. Despite Roger's warnings, Jerry becomes infatuated with Marcia Van Wyck, an idle-rich temptress who teaches him how to kiss, but thoughts of Una still linger. At a party, when Jerry catches Marcia kissing Ballard, he throws Ballard over a bannister, thus disrupting the evening. Jerry repulses Marcia's advances, tears her dress down the back, and returns home. Roger arranges for Una to appear at the spot where they first met, and they are reconciled.
