Description
Jim Hawkins (Kim Burfield) is a young boy who works at a pub with his mother (Maria Rohm). When a drunken old sailor named Billy Bones (Lionel Stander) comes in for a drink and dies, Jim gets his hands on a map which shows the whereabouts of pirate Captain Flint's treasure. Immediately taking action, he then enlists the help of Squire Trelawney (Walter Slezak) and Dr. Livesey (Angel DelPozo) to join him as he locates the island on the map. Together, they join a ship commanded by Captain Smollett (Rik Battaglia) that will lead them to their destination.
Word of the treasure map gets around and most of the crew are recruited with the help of the ship's cook, Long John Silver (Orson Welles), an ex-pirate who had sailed with Captain Flint and intends to get the treasure by mutiny and murder.
Already on the island is a marooned pirate, Ben Gunn, who has spent his time on the island gathering the treasure. With his help Jim, the Squire, the Doctor, the Captain and a number of loyal crewmen outwit the pirates, killing most of them in gun battles.
Silver is captured, but escapes when the ship reaches harbour in the West Indies. Much of the plot and the linking narrative – spoken by Jim Hawkins – is faithful to the original book.
