Pluft is a teen ghost who is afraid of people, about the courage that comes forth from fear, and about the affection that grows despite differences. Pluft was never alive and he has a ghost mother and father. But since his father died and turned into blue cellophane at the theater he haunted, the family moved to an old house, at a lost beach, in a faraway land. There, Pluft and his mother live with his uncle Gerund, a retired sea ghost. One day, Pluft meets Maribel, an orphan girl as lonely as he, who has been kidnapped by a pirate in search of her grandfather's hidden treasure. Pluft must overcome his fear to help his new friend.
