But this romance jeopardizes the ambitious plans of Beto's ex-girlfriend and a devious bawd who will do anything to put an end to the musician's infatuation. In order to save her life, Luiza leaves her little children behind, flees the country and becomes DJ Ariella. Years later she comes back to fight fiercely for a second chance at reuniting her family, unaware she will soon meet again the love of her past and her tormentors.

The conflicts involve both the faculty and the student body and, in this scenario, Education emerges as a hope, reminding everyone that it is never too late to have a second chance.
