A little kid-ghost called Pluft lives with his ghost-mother and ghost-uncle, in a remote house in a desert island. He doesn't even believe people real exist. His world will be thrown upside down, when an evil pirate (Perna de Pau) disembark on the island, after kidnapping the little girl Maribel (daughter of a famous captain), in search of Captain's hidden treasure. Three friendly sailors will help to free the girl. Based on a very well known Brazilian children's play.—celsoaojr

Pluft shows the unexpected friendship between the ghost who is scared to death of people and the girl Maribel. She is kidnapped by the pirate Perna de Pau, who wants to use her to find the treasure left by her grandfather, the late Captain Bonança Rainbow. In the abandoned house where the old man lived, Maribel waits for the help of the sailors Sebastião, João and Julião, very friends of the old captain, who go out on a clumsy search for the girl.
