Changing the black and white piano keys is like changes in human life.
The young talented heroine of the film, ROSA, has to make sure of this just at the moment of fame - during the performance when she was solo playing the piano. To the enchanting sounds of her music, she realizes that she is losing her hearing in the hall full of enthusiastic listeners.
Is deafness, like a black piano key - a punishment or a test? - a question which the heroine herself and the audience of the film will have to answer.
The heroine's life is changing - deafness intensifies in the chords of the silence that oppresses her. In a state of mental crisis, the girl leaves London, leaves the bustle of the city to the island of Tenerife. She goes to the seashore, where the breath of the ocean can excite the human spirit, sharing strength and hope.
ROSA leaves to meet and submit to two elements - love and the sea, near which she meets a young fisherman who is no less in love with music than she is. Overcoming confusion and pain, ROSA is experiencing a new stage of true inspiration, evoked by the sensitive music of the sea and the great, all-conquering feeling of love.
What awaits her among these two elements that can reconcile her with the world of hearing ones?
Will ROSA manage not to lose faith in herself with the support of her beloved and to catch the harmony, breathing in the sensitive blue radiance of the healing ocean?
