An old sailor, calling himself "the captain" but really called Billy Bones, comes to lodge at the Admiral Benbow Inn on the English coast during the mid 1700s, paying the innkeeper's son, Jim Hawkins, a few pennies to keep a lookout for "seafaring men." One of these shows up, frightening Billy (who drinks far too much rum) into a stroke, and Billy tells Jim that his former shipmates covet the contents of his sea chest. After a visit from another man, Billy has another stroke and dies; Jim and his mother (his father has died only a few days before) unlock the sea chest, finding some money, a journal, and a map. The local physician, Dr. Livesey, deduces that the map is of an island where the pirate Flint buried a vast treasure. The district squire, Trelawney, proposes buying a ship and going after the treasure, taking Livesey as ship's doctor and Jim as cabin boy.
