Woods' boyfriend, Warner Huntington III, the son of a U.S. congressman, breaks up with her the night she expects him to propose, claiming that he needs "to marry a Jackie, not a Marilyn." Warner is bound for Harvard Law School, and Woods becomes determined to gain admittance to the school to win him back.
