What are the main conflicts in the first act?

The important events in All My Sons have already transpired. The only action that occurs within the time frame of the narrative is the revelation of certain facts about the past, and it is important to track how the revelations change the relationships among the characters as well as their own self-definition. The explanation of Keller's and Steve's business during the war, and the ensuing scandal, is revealed through insinuation and association. There are also conflicts surrounding Mrs. Keller and her illusions around her dead son. The first act also illustrates the tensions between the characters that will rise to the surface in the second and third acts. The Kellers seem like a happy family at first; it is even remarked that Chris is the rare sort of person who truly loves his parents. But there is resentment beneath the surface of their contented existence, resentment that reflects more than just grief at the loss of a son. The relationship beetwen Chris and Ann is also a factor.
