Percy Schmeiser, a farmer, battles Monsanto after their GMO canola seeds contaminate his fields. Despite losing in court, he countersues and campaigns for farmers’ rights. Monsanto’s resources intimidate him, but he opposes GMOs, questioning their safety. The legal system fines farmers using Monsanto’s seeds, but the Supreme Court rules Percy isn’t liable for $200,000, affirming Monsanto’s ownership. Percy vows to continue fighting.
