Throughout the movie, character introductions are shown through dossier-like cards, which, among other traits, label them as "not married" (a reference to Seventeen Moments of Spring).

Billy Bones, an allergic and alcoholic pirate, in animated form, surprise-attacks Flint and takes the map.

He asks the innkeeper, Jim Hawkins, to notify him should an old one-legged sailor arrive, unaware that a pirate gang is spying on them.

Dr. Livesey, an always-jubilant doctor, hospitalizes Bones after his sneezing knocks a ceiling plank loose, injuring him, and, along with his alcoholism, also causes a stroke.

Afterwards, Bones warns Hawkins that the locked chest contained in his room is in danger of being stolen by pirates, charging him to flee with it to the estate of Squire Trelawney for protection, should they arrive.

Fearing the pirates' arrival, Hawkins takes the Black Spot, and the map from the chest, and flees from the inn.

Pew, Black Dog, and the rest of the pirate gang return to raid Bones's chest for the map, but discover only gold coins inside.

Pew tries to persuade the pirates to find the map, but he accidentally trips himself into a barrel, and careens off a sheer cliff to his death in the ocean.

Trelawney calls on Silver, who offers his ship, the Hispaniola, and his crew (who turn out to be Pew's pirate gang in disguise), for the voyage.

Despite this, Hawkins escapes, absconds a dinghy, and attempts to row to the island alone, but Silver and a complement of the crew chase after him.

At daybreak, they find the burial spot indicated on the map, but Livesey, Gunn, Trelawney, and Smollett have set up an ambush.

The pirates, sans Silver, attempt to escape by running, but encounter Livesey, who examines them, and finds that their pipe smoking has deteriorated their health.

Successful in their mission, the remaining crew loads the treasure onto the ship and sets sail back to England.

The film features musical interludes with live actors that explain, for example, the evils of drinking alcohol or smoking.

A public outcry over this prohibition resulted in an exemption for "movies that have significant historical and cultural value", including Treasure Island.

A United States direct-to-video cut from 1992 was published in the US under the title Return to Treasure Island on DVD (Region 1).
