Aaron Cole, a PhD, becomes a Chinese teacher at Hamilton University, mocked by students like Will. He makes a ten-question bet, defeating them. Board director Mr. William pressures him to resign, but his mentor, Irving Shaw, supports him. Three linguistics professors challenge him and are defeated. Aaron returns home to launch a free online charity Chinese course; students beg him to stay. At the airport, Leo aspires to be a Chinese teacher. Aaron makes a pinky promise, 'passing the torch.'
