In 1850, Nantucket is the center of the whaling industry. For Ishmael, Pip, and Queequeg, it’s the beginning of a perilous journey aboard Captain Ahab’s Pequod. A veteran whale hunter who lost his leg to Moby Dick, Ahab wants revenge. He’ll stop at nothing to kill his nemesis. When the harpooners of the Pequod kill one of the white whale's companions, the seamen get an idea of the anger and power of their enemy.
