Danger is a daily reality for Ken Roberts and the European immigrant families who scratch out a living in the deep coal mines of Wyoming Valley, Pennsylvania. In a camp of Lebanese immigrants, Rosalind Gilbran lives with her grandfather and grandmother. Ken takes a walk on the mountain and meets the beautiful Rosa. After a few more chance meetings, Ken gives the petite gypsy a Bible and tells her about his Savior. When Rosa’s grandparents discover she has been secretly meeting a “coal cracker,” they hastily accept an offer of a marriage contract for Rosa to a cruel and hot-tempered man. Rosa’s only desire is to run away … but Ken finds her in the woods and convinces her to return to her grandparents. But will Ken’s advice mean he’ll lose Rosa forever?
