With operations in 46 countries, Monsanto is the world leader in genetically modified organisms (GMOs). Since its founding in 1901, the multinational has faced many legal challenges due to the toxicity of its products. Today, it is reinventing itself as a "life sciences" company converted to "sustainable development." Using unpublished documents and first-hand accounts by victims, scientists and politicians, the film exposes hidden aspects of this industrial giant. Thanks in part to lies, collusion with the US government, pressure tactics and corruption, Monsanto has been spreading GM crops worldwide with no real monitoring of their effects on nature or human health.
