In 1850, author Herman Melville visits innkeeper Thomas Nickerson, the last survivor of the sinking of the whale-ship Essex, offering money in return for his story. Nickerson initially refuses, but then finally agrees when his wife intervenes. The story turns to 1820: a whaling company in Nantucket has refitted the Essex to participate in the lucrative whale oil trade, and 14-year-old Nickerson signs on as a cabin boy. The owners hire veteran whaler Owen Chase as first mate, though he is disappointed not to receive a captain's commission. The captain is George Pollard, an inexperienced mariner from an established whaling family who envies Chase's skill and popularity. Chase and Pollard clash, leading Pollard to sail into a storm against Chase's advice. The two agree to put their differences aside, rather than risking their reputations by returning to port without profit, and soon, the crew kills their first bull sperm whale.
