The owners of the farm are friends of Abraham, his maternal grandfather, who has been living in London for ten years. Abraham visits the farm from time to time but without paying much attention to his grandson.

Abraham can no longer question the genocide of the Jews and realises that he has probably no other family left than Simon, with whom he was often very hard.
