A poor but beautiful woman comes to the city looking for her husband ... who is married to another woman, the evil Gloria. While she falls in love to a handsome and good hearted doctor, she decides to work at nights to earn money at a "Model School" which is, in reality, a high profile brothel...

The story is set at a prestigious, but rigid and repressive school called Instituto Vidal. Its strict owner, Julia Vidal, was once kind but has now turned into a bitter woman following the death of her husband and her daughter, Lauriel. Her granddaughter, Ana, a very sweet and intelligent 10 year old, also has been affected by the death: She has been rendered virtually speechless by the trauma, though she expresses herself through music and possesses an extraordinary ability to move objects with her mind. Ana's unscrupulous father, Francisco Capistrán, however, has taken advantage of the situation to try to steal Julia's school. The timely arrival of Ana's uncle, Salvador, Amanda and her adopted son changes everything. Ana’s sad and lonely life takes an unexpected turn for the better and she regains her joy in a series of adventures bursting with humor, excitement, music and thrilling surprises.
