Forrest Whittiker, in any role, is worth a look. That said, while this movie may be a work of fiction, there are Big Corporations right now, trying to gain control of water rights in several western states. There is a small city in Washington State, where people have been prosecuted for catching rainwater in barrels; prosecuted because "the water belongs to the city." While this movie may be fiction, the premise behind it is not.
A former CIA operative turned political talk show host is hired by a corporate whistle blower to expose her company's cover-up of a massacre in a South American village.
