In 1976, Argentina fell into the hands of a de facto government. Thousands of citizens are persecuted and kidnapped. This is the case of the parents of two children, who, knowing they are wanted, decide to hide.

A young working mother in Buenos Aires, Ana reads a note suggesting a relationship kept hidden by her husband, an executive preoccupied by his job. To solve the mystery she travels a long distance to Rio Escondido, an unimportant river town at the foot of the mountains in western Argentina, and the film becomes a journey of discovery as she finds her heart and her passion. Along the way, truths and perceptions intertwine when Ana meets Martin and she learns who and what he is.

The story takes us on a journey of tributes to the greatest bandoneon player of Buenos Aires, Aníbal Troilo, through interviews, musical sequences, dance and the powerful presence of football. The film intertwines fiction and testimonies to reveal to us a brilliant musician.
