As soon as Mauro, an Administration student, discovers a strong vocation for mediumship, he drops everything to go deeper and dedicate himself to Umbanda, a religion he embraces so strongly that it makes him give up his studies. Determined to open his own spiritist center, Mauro moves to the countryside.
