Bad Company (1925)

When young Gloria Waring's wealthy father dies, she discovers that her brother--who is heir to the family fortune--is about to marry a well-known golddigger named Teddy Lamont. Gloria steals the will from her father's attorney, James Hamilton, so Teddy won't find out how much money her future husband will inherit. Hamilton finds out about her theft but is unexpectedly sympathetic to Gloria about it. It turns out that Hamilton has reasons for his behavior, and when Gloria discovers why, complications ensue.
