Punk musician Carlos decides to set out to find out about his family history when his adoptive father Genaro dies. He leaves Buenos Aires with the bandoneon of Genaro as his only company and sets out for Los Angeles, a wind-shaken village in the middle of nowhere of the Argentinian pampa. After some troublesome quest, he finds there not only the secret of his origin, but also the love of this life and his own tune, which combines his past as punk drummer with the traditional elements borrowed from cumbias, chamamés, and criollo valses.
After the death of the village pharmacist, his widow Lina only inherits debts that he must face. Valentin, the old shoemaker, is the main creditor and the exuberant Lina must pay him what he owes, whatever it costs.
The action takes place in Comodo Rivadavia, and reenacts a 1907 mission lead by José Fuchs, who was supposed to find water but found oil instead.
