440 Hz by Nacho Diago is the story of Cecilia, a deaf-mute girl who lives with her mother in a wealthy city suburb, in a state of extreme overprotection. One day she reads a poem by her father, a writer who left them some years earlier, and which she interprets as a call to action. The inherent rebelliousness of a 17-year-old girl and her frustration with her family situation prompt her to head off on a quest to find out the true reasons for her abandonment.

But in this performance, as in life, things are not always what they seem.
