In this film, a lonely mother and her son go to the opera where a performance of Cherubini’s opera Medea is given. It is the mother’s birthday and she wanted to surprise her son by inviting him to the opera. But, the son’s plan were different and he is quite upset about it. His mother tries to break the silent barrier behind which he hides. A semblance of discussion begins, not without humour. Tension is present but, as the performance goes on, both find themselves astounded, captured, alone in the opera house.
