The Adorable Cheat plot
The daughter of a wealthy industrialist wants to take over the company when her father retires, but the father, an old-fashioned type who does not believe that "girls" belong in the business world, plans to leave the company to her dissolute brother. To prove to her father that she can do the job, she disguises herself as an ordinary 'working girl' and gets a job in her father's factory. There she meets a clerk and falls in love with him. She brings the young man home to meet her parents, but in the evening the family safe is robbed and all signs point to her new boyfriend.
