After more than twenty years living together, Daniel, a music teacher and a pianist, and Ana, who runs an art gallery, are going through a sentimental crisis.
Daniel is now living on his own and wants the divorce, while Ana refuses to come to terms with reality. The situation eventually affects their daughter Mónica, who, after finishing her training as a journalist and seeking a job in vain with her boyfriend David, feels particularly sensitive these days.
Music, on the other hand, seems to be Daniel´s only comfort. He is ill at ease with himself and with others and is having a far-from-idyllic relationship with Clara, a married woman who awakens Mónica´s curiosity.
One night, Mónica experiences an embarrassing and incomprehensible situation which also involves Daniel, Ana and Clara..
