Alma and José are two young people who try to succeed and achieve their goals in life, in spite of the odds and difficult circumstances they were born into, surrounded by poverty, economic disparity, homeless street children and substance abusers.
Alma lives with her mother Mercedes, who led her daughter to believe that her father Eusebio died, but the truth is that he left them long ago and now lives with another woman. José, meanwhile, is a boy who dreams of being a great Olympic swimmer, just as Alma dreams of becoming a famous ballerina.
Despite the hostilities they are forced to endure daily, Alma and Joseph don't stop trying to succeed and achieve their dreams, even if they have to go through misfortunes and sufferings.
