Night Into Morning (1951)

Philip Ainley is a happily-married English teacher at a major USA university, whose life is turned upside down when his wife and child are killed by an explosion and fire in their home. Ainley's associate teacher, Tom Lawry, and the secretary of the department, Katherine Mead, a widow, do what tan to comfort him after the tragedy. As time goes by, Lawry thinks that nothing further can be done and becomes jealous of Katherine's continued efforts to help Ainley. Ainley, following an outward calm during the funeral and following days, tries to escape his sad anxiety through alcohol, and then via a suicide attempt.
