When young Joanna Drayton (Katharine Houghton) brings her new fiancé, Dr. John Wade Prentice (Sidney Poitier), home to San Francisco to meet her liberal parents (Spencer Tracy, Katharine Hepburn), their progressive leanings are put to the test when they discover the man their daughter has chosen to settle down with is black. Also attending the Draytons' dinner are Prentice's parents (Roy E. Glenn Sr., Beah Richards), who vehemently disapprove of the relationship. The film earned Academy Awards for Katharine Hepburn and screenwriter William Rose.
