Sunday Jews explores a family united in blood yet divided by ideas. Charles, the eldest son, hopes to be a Supreme Court justice; family beauty Nell has children by different lovers; art expert Erika has altered her appearance, yet clings to her role as custodian of the family's Jewishness; and artist Zach has two wives. Their mother, infamous in Israel, born of a well-to-do Boston family but no longer rich, is bound to a past that never quite dies. The buried history of this extraordinary - and very American - family comes to light unexpectedly when grandson Bert brings home as a wife the woman who, some years ago, joined the family circle and then mysteriously disappeared.
