A skipper of a 19th century whaling boat is obsessed with the idea of harpooning the whale that is responsible for the loss of his leg.

Captain Ahab sails the seven seas seeking revenge on Moby Dick, the great white whale who maimed and disfigured him.

Ishmael sees his dream of a whaling voyage come true when he joins the crew of the Pequod, a sailing vessel leaving port in Nantucket. Unbeknownst to Ishmael and the mates, the Pequod's monomaniacal Captain Ahab is taking them all on a mad and personal mission to slay the great whale Moby Dick, an obsession that will open their eyes to the wonder and spectacle of man, of beast, and the inescapable nature of both.
