An Irish maid falls for the son of her wealthy boss, though their disapproving fathers and a bitter strike at the steel mill complicate matters.

Mary Rafferty comes from a poor family of steel mill workers in 19th Century Pittsburgh. Her family objects when she goes to work as a maid for the wealthy Scott family which controls the mill. Mary catches the attention of handsome scion Paul Scott, but their romance is complicated by Paul's engagement to someone else and a bitter strike among the mill workers.—Daniel Bubbeo <[email protected]>

The Raffertys are immigrant Irish laborers living in Pittsburgh. Their patriarch, Patrick Rafferty, is wheelchair bound due to an industrial accident incurred at the Scott family steel mill. He blames the accident on working conditions at the mill and thus he hates the Scotts despite the fact that they have more than adequately financially compensated Patrick. So Patrick is not too happy when his daughter Mary goes to work as a domestic in the Scott household. Despite Mary's lack of experience, she quickly becomes close friends with the entire family of parents William and Clarissa, and children William Jr., Paul, Ted, and Constance. It is Paul from whom she attracts the most attention; the two fall in love. But Mary does not want to risk Paul's social standing and with the help of Clarissa decides to place some distance between herself and Paul. When William Sr. notices Paul's total obsession with work and the reason for Mary's departure, he decides Mary's return would be the best thing for Paul. After Mary returns, a strike occurs at the mill. Paul and Mary try to broker a deal between the Scotts and the workers, most of whom are friends of the Raffertys. An undelivered communique results in tragic consequences. Despite still being in love, Paul and Mary realize a union between them is now impossible. Making other life choices - an especially unhappy one for Paul - Mary and Paul may still be able to eke out a life together due to a move by Clarissa, the move solely in an effort to ensure the continuation of the Scott name with the mill.—Huggo
