Tony is an uneducated Brooklyn teenager. The highlight of his week is going to the local disco, where he is the king of the dancefloor. Tony meets Stephanie at the disco and they agree to dance together in a competition. Stephanie resists Tony's attempts to romance her, as she aspires to greater things; she is moving across the river to Manhattan. Gradually, Tony also becomes disillusioned with the life he is leading and he and Stephanie decide to help one another to start afresh.
