Sino ang Maysala?

Don Ramon killed himself because of his bankruptcy, leaving his wife, Rosa (Rosa Mia), and their four children, Carmen (Paraluman), Gloria (Gloria Romero), Lolita (Lolita Rodriguez), and Bobby (Romeo Vasquez) with nothing. In order to fill the void left by her father, Carmen, the oldest, promised to send her siblings to school. One by one, Carmen sold her jewelry until everything was gone, except for a pendant that featured a picture of her former partner, Rod (Rogelio de la Rosa). She suddenly ran across Rod in a nightclub one evening. Rod, who was now married, still harbored feelings for Carmen. However, Rod's marriage to his wife, Bella Flores, was in ruins, and his fortuitous encounter with Carmen inadvertently reignited their strained connection.

Before Carmen's family learned about their unlawful connection, everything between the two lovers was going well. Gloria and Lolita avoided Carmen because they were angry, irritated, and humiliated of what had transpired, but both sisters also had their own issues. In the midst of all these controversies, the young and vulnerable Bobby quickly turned violent and disobedient. After engaging in minor altercations and thefts, he quickly turned to criminality. He was apprehended and tried. He attributed all of his tragedies and sufferings to his family.
