Benjamin Braddock is a rather unwilling guest of honor at a party thrown by his proud parents to celebrate his graduation from college. But the phoniness of his parents' world overwhelms him and he flees--straight into trouble. Mrs. Robinson, wife of his father's law partner, has designs on young Ben. After a couple of false starts, they begin a clandestine affair, which falls apart when Benjamin meets her daughter Elaine. The two fall madly in love, but Elaine's parents conspire against them. After learning of her mother's affair with Benjamin, Elaine flees to a more sane relationship--with Ben in hot pursuit. Elaine is in the process of marrying her stodgy fiancée when Benjamin rushes into the church, abducts the now-willing Elaine and the two happy lovers escape--by hailing a passing bus.
