In a time of heightened personal opinion about oil and agriculture industries, this film helps shed light on some hard truths about both. Olmos uses apparently true events to create a narrative of an aging farmer from a dusty town struggling with the problem of the groundwater he uses for irrigation being polluted by a negligent oil company - a company, with any probability, that holds the farmer hostage as he relies on big corporate oil to fuel his day-to-day operations.
