What was the story of "Death of a Salesman"all about?

Death of a Salesman is a story about family dynamics.... a demanding father, his loving and concerned wife, and their two adult sons, who are estranged from their father. Over the course of the play, we see Willy Loman struggle with the changes in his job, his desire to take care of his family, his sons' anger and disillusionment, and his wife's struggle to keep it all together (family).
