Persistent white trails behind aircraft, first noticed in the United States and Canada more than twenty years ago, are the starting point for this film's case that governments and militaries are secretly seeding the atmosphere with metallic particles and microorganisms. It tracks the claim from North America to Europe, Africa, and Asia, pairing footage of sky trails with interviews from people who link the rise in Alzheimer's, cancer, autism, and MS diagnoses, along with die-offs in trees and animals, to what they call illegal spraying of barium, aluminum, and lithium. Officials and scientists on camera deny any such program and insist the trails are ordinary contrails, and the film sets their denials against documents it says the French army later removed from public view. No large-scale cause-and-effect proof is offered; instead the film builds its argument from testimony, aerial photography, and the gap between official reassurance and public suspicion, leaving the viewer to weigh whether that gap amounts to evidence or coincidence.
