In 1947, a daring Norwegian explorer sets out to prove a controversial theory that could rewrite history. Pal Sverre Hagen stars as Thor Heyerdahl, a determined ethnographer who believes that ancient South Americans could have crossed the Pacific Ocean and settled in Polynesia aboard a primitive balsa wood raft. Despite widespread ridicule from the scientific community, Heyerdahl assembles a small, eclectic crew including his childhood friend (played by Anders Baasmo Christiansen) and a skeptical engineer (Gustaf Skarsgard) to undertake an audacious 4,300-nautical-mile voyage. Together, they christen their handmade raft Kon-Tiki and launch into the vast, unpredictable ocean, facing treacherous storms, hungry sharks, and the constant threat of dehydration and despair. Directed by Joachim Ronning and Espen Sandberg, this gripping drama captures the raw beauty and peril of the open sea while exploring the indomitable human spirit. As days turn into months, the crew's bonds are tested and their sanity pushed to the brink in this thrilling true story of courage against all odds.
