A twenty year-old youngster vows to look after his 3 sisters after the loss of their parents. Time passes and now Augusto is married to the gold digger Margarita, who despises his caring nature and most of all his 3 sisters.

Augusto becomes the head of his family and vows to look after his 3 sisters - Silvia, Lisa and Beba, after the loss of their parents. Silvia is married to Carlos, an unemployed actor and they have 2 twin daughters. Lisa is studying to become a doctor and is working as a nurse in a hospital. She encounters Santiago, a handsome engineer, who is working for a construction company that is trying to buy the land, belonging to the hospital to build a mall. Margarita is fed up with Augusto, his sisters and his principals, so she sets her eyes on Santiago. But the handsome engineer is engaged to Barbara, the daughter of his business partner.—Lara Cain
