Plot

Oscar Grubman, the fifteen year-old prodigal son of Columbia University history professor and author Stanley Grubman, is taking the train home from the Chauncey Academy for Thanksgiving; he is seated with his good friend Charlie. An attractive girl from his school, Miranda Spears, approaches him seemingly with interest and asks him what he's reading. Oscar politely brushes her off telling her that is a work by Voltaire, later explaining to his shocked chum, Charlie, that he is in love with another woman, and that he plans to win her heart this break.

They arrive in New York City and share a cab to their respective houses; Oscar parts from Charlie at his apartment were he is greeted with the nickname "tadpole" by the doorman Jimmy, lending the title of the movie. Oscar introduces us to his dad, the work-obsessed writer, Stanley, and stepmother, the passionate doctor Eve. That evening the Grubmans hold a party; Oscar's dad introduces him to a girl of his age, but Oscar is in love with someone more mature.
