Avec le génie génétique, l'industrie agroalimentaire se promet d'implanter une nouvelle technologique pour une "alimentation mondiale" propre et plus efficace. L'augmentation du rendement et l'adaptation des semences aux bouleversements climatiques futurs apporteraient, selon son argumentation, une contribution essentielle à la sécurité de l'alimentation mondiale. À l'exemple de la culture du soja au Paraguay, le film montre le caractère problématique de cette politique.

Beautifully shot and interweaving interviews with scenes from soy fields in Paraguay, "Raising Resistance" explores Latin American farmers’ struggle against the expanding production of genetically modified soy in South America. Biotechnology, mechanisation, and herbicides have radically changed the lives of small farmers in Latin America. For farmers in Paraguay this means displacement from their land, loss of basic food supplies, and a veritable fight for survival. Geronimo Arevelos and a group of small farmers stand defiantly in a corporate-owned soy field adjacent to his own, blocking a tractor from spraying herbicides that will decimate his crops and expose nearby families to toxic chemicals. As corporate farms seize farmland and rapidly expand production of genetically modified soy, Geronimo and the campesinos find themselves in a life and death struggle. Raising Resistance illustrates the mechanisms of a global economy that relies on ‘monocrop’ agriculture and corporate ownership of land. In telling the story of Paraguay, "Raising Resistance" poses the larger question of whether the global community wants to go on living with a system that allows one crop to prosper at the expense of all others
