Crude secrets about the Cantarell oil field, Mexico's most prolific offshore oil reserve, are portrayed in reverse in the visionary documentary Pozo. The mysteries of the bastard family of the fisherman who discovered the country's greatest energy treasure are accompanied in chorus by the intrigues, apparitions and petrosexual traumas of the inhabitants of Ciudad del Carmen, an island radically transformed by the voracious hydrocarbon industry. The chants of the gods of darkness, of crude oil and of the end of time, accompany and guide this return to the eternal source of emptiness. This invocation does not count the facts from the end to the beginning, but undoes them, diminishes them, de-refines them, decreases them, deconsumes them, de-extinguishes them.
