A man discovers that the second child he is expecting is the product of his wife's infidelity, who dies in childbirth. The boy, named Alberto, is treated as if he were a servant. His brother José Manuel, on the other hand, is treated well and all his whims are fulfilled and therefore he becomes lazy and irresponsible.
