The documentary recounts an important part of the history of this country, retracing a long journey that began on October 6, 1924, and continues to this day. On that day, radio took its first tentative steps into our homes, broadcasting a brief official announcement followed by the inaugural concert of Haydn's Quartet Op. 7. At that precise moment, we imagined that a child was born in a working-class neighborhood of the capital, whose voice would accompany us throughout this journey.
