Esteemed university professor Ellen Taylor marks her 25th wedding anniversary. For the celebration, the whole family gathers: the eldest daughter, a popular comedian; the middle daughter, whose husband is a successful lawyer; the youngest daughter, a high school student passionate about biology. Asin brings his new partner Elizabeth. Ellen recalls that this woman was her student, with whom she had a conflict over political views, and she was forced to leave the institution. Two years later, the family again gathers for the celebration, and a popular book written by Elizabeth begins to influence public opinion.
