Photographer and researcher Rodolphe Guignard embarks on a daring journey around the world to debunk myths about aquatic killers. He dives with sharks in Florida and the Bahamas, demonstrating remarkable interactions. In Mexico, he studies how humans and crocodiles coexist, discovering that these ancient reptiles are curious and rarely dangerous. Concluding his adventure, Guignard plunges into the icy waters of Norway to explore whether it is possible to live peacefully alongside orcas — intelligent predators whose fate is closely tied to our own.
