Ana is a 14-year-old girl living in Buenos Aires with her father, Javier. During the winter holidays, Ana starts to feel mysterious vibrations in the metal plate she has in her arm from an accident she suffered as a child —and together with her friend Lepa, she playfully composes music to the beat. Later, however, Ana discovers that the mystery is even more intriguing: the vibrations are actually Morse code. Obsessed with deciphering the message, the young girl grows distant from her father and her friend.

Winner of the best Iberoamerican film award and the best actress award —for Sofía Clausen— at the Malaga Film Festival. It was also presented at the Berlin International Film Festival.
