However you do get to see the 19 year old Mary Pickford dressed in tight sailors trousers showing her rarely seen fine figure and physical attractiveness. Interesting to see it for usually she is covered in large dresses or rags in her films.
Sailors on a ship have a treasure map and are discussing it down in their cabin. The Cabin Boy spies where they put the map and steals it and shows the captain. The sailors mutiny; the Cabin Boy and the Captains daughter (Mary Pickford) flee to an island, where the treasure is buried. Pirates come out of nowhere and grab them and kidnap Mary Pickford as well (who wouldn't) and, the boy endeavors to save her in the night but gets caught too. The boy gives the pirates the treasure map.
The mutinous sailors from the ship find the island and the treasure first. They have a fight with the pirates and all die.
While this was happening the Cabin boy and Mary get back to the ship, free the captain and crew and take them to the treasure - the pirates and mutineers having already killed each other the treasure is left to them.
The kids get married (he looks really young!) AND the BIG surprise surprise - look away if you don't want to know what happens next. The boy was dreaming it all.
Poor editing effort but you do get to study a few actors. Mary Pickford this early displays her natural habit of being a person who likes to touch, grab hold of people. She does it to the pirate at one stage in this piece subconsciously and monetarily and pulls back her hand realizing that it was not appropriate to the scene. It does hint though that when the Director called action Pickford buries herself in a piece.
