Steel separates 1873 Pittsburgh into rich and poor, master and worker, powerful and powerless. On one side is Paul Scott, the progressive son of a steel mill owner. On the other is Mary Rafferty, daughter of an embittered laborer who was crippled in a mill accident. When Mary takes a post as housemaid at the Scott mansion, she and Paul fall desperately in love. But a bloody strike may tear the city - and the lovers - apart. Surging with passion and strife, featuring a commanding cast that includes Greer Garson, Lionel Barrymore and Gregory Peck (the relative newcomer created a sensation as the romantic, intense Paul), The Valley of Decision is a prime example of prestige filmmaking during Hollywood's Golden Age.
