Synopsis

Septimus Kinsolving's speculations cause the price of bread to rise dramatically. Mary Boyne's father is forced to close his bakery because of the turn of the market, and he goes insane. Mary's brother becomes involved in crime and is arrested for murder. Mary then is forced to live amid squalor and loneliness. Meanwhile, Kinsolving has died and his son Dan collects the fortune. When he discovers how the money was accumulated, Dan's conscience spurs him to right the wrong that was done. He meets Mary and falls in love with her although she dislikes him. When Dan brings about her brother's acquittal and her father's recovery, Mary comes to love him and they are married.

Notes

The Variety review erroneously places Jerome Patrick in the film's cast. Moving Picture World gives the scenarist's name as Gertrude H. Bergen, not G. Marion Burton.
