In the Heart of the Sea tells the incredible true story of the whaleship Essex, which was attacked and sunk by an enormous sperm whale in the Pacific Ocean in 1820. The crew of 20 men was forced to abandon ship and cram into three small whaleboats with little food or water. They faced starvation, thirst, and desperation during their 90-day ordeal at sea, making impossible choices to survive. This real-life disaster inspired Herman Melville's famous novel Moby-Dick and remains one of history's most dramatic tales of survival against all odds.
