In 1820, crewmen (Chris Hemsworth, Benjamin Walker, Cillian Murphy) aboard the New England vessel Essex face a harrowing battle for survival when a whale of mammoth size and strength attacks with force, crippling their ship and leaving them adrift in the ocean. Pushed to their limits and facing storms, starvation, panic and despair, the survivors must resort to the unthinkable to stay alive. Their incredible tale ultimately inspires author Herman Melville to write "Moby-Dick."
