Mariana Junqueira is the young and powerful President of the Junqueira Group, but behind the empire she commands alone, she has never stopped searching for the man she loved and lost — the father of her daughter, Tati. Miguel Carvalho, for his part, lives as a simple construction worker, supporting his sick mother and keeping half of a necklace that hides the truth about his origins. When fate brings them together at a construction site, Miguel is humiliated by the elite and persecuted by Paulo, his adoptive brother who wants to take everything from the Junqueira family. But the man everyone calls a poor nobody holds a secret capable of turning the tables: he is the lost heir of the Serrano Group, and his return can bring down all those who tried to keep him down.
