The main character, young Jim Hawkins, helps his parents run the Admiral Benbow, an inn near Bristol, England. One day a desperate-looking ruffian, Billy Bones (“the captain”), appears and takes a room. After being visited by a former mate named Black Dog, Billy suffers a stroke. Later, while drinking rum, he tells Jim that he is a pirate and that he has a treasure map. However, Billy fears that another pirate might mark him with a black spot (a summons or threat). Shortly thereafter, Jim’s ailing father, who is being tended to by Dr. Livesey, dies. A blind beggar, later revealed to be the pirate Pew, subsequently arrives and puts something in Bones’s hand. After Pew leaves, Billy has a fatal stroke.Jim and his mother open Billy’s sea chest, taking the money owed to them as well as a packet, before fleeing. A group of pirates led by Pew descends on the inn, but they are soon scared off by the sound of approaching horses; Pew is trampled to death. Believing that the pirates were searching for the packet, Jim seeks out Dr. Livesey, who is with Squire Trelawny. The packet is revealed to contain a treasure map, and the three decide to mount an expedition to Skeleton Island to find the hidden riches. However, they are fooled into hiring some of Billy’s former shipmates, including the leader of the pirates, Long John Silver.
During the voyage, Jim overhears Silver and his men planning to steal the treasure once it is found and to kill all of the non-pirates. What follows is a rip-roaring tale of mutiny, treachery, swordfights, and murder as Jim, Dr. Livesey, and the squire are forced to live by their wits in order to survive against ruthless enemies. They are aided by Captain Smollet and by Ben Gunn, a pirate marooned on Skeleton Island. Jim and the others ultimately prevail over the pirates and return home with the treasure. Silver notably escapes with some of the money.
