The Silver Cord (1933)

Married for five months, Americans Christina and David Phelps, a biologist and aspiring architect respectively, live in Heidelberg where Christina has been working in a research lab, this stint in Europe being two years for David where he has been able to stretch his wings to start to find his own footing. They decide to move back to the US, specifically to New York City, when David is offered a job there with one of the most prestigious architecture firms and where Christina had previously been offered a job with the Rockefeller Institute. They decide to make an extended visit to the Phelps country home en route so that Christina can meet his family of his long widowed mother, his younger brother Rob, and Rob's fiancée Hester. What Christina is unaware of is that she is in for the biggest fight of her life in Mrs. Phelps, a manipulative, controlling woman who has substituted her two sons for the lack of happiness in what was her own marriage, her expectation that they will be solely by her side for the rest of her life. There are a few things working on Christina's side as compared to Hester, whose own engagement to Rob is also threatened: a few years in age and thus experience; the fact that she and David are already married with a child on the way; and that unlike Rob, David has had those two years away from his mother when he may have been able to see her actions more clearly in being for her own selfish goals than for either him or Rob. But even these items may not be enough to overcome David's "love" for his "self-sacrificing" mother.
