Javier Aguirre
"El Cocosabio", "La Gandula" and "El Torralba" are three pianists, not in the musical sense of the word, but in the police sense. All three have "played the piano", that is, they have left their fingerprints on the corresponding police record. But, without underestimating our characters, it must be acknowledged that their criminal activities are second class. Everything changes with the arrival of "El Tizona", a former small-time crook who has furthered his studies abroad and returns to Spain perfectly retrained and converted into a dangerous gangster. At least that is what he and his friends believe. (from Enciclopedia del Cine Español, translated by Google, which seems to be accurate for once)
