Captain Barracuda is obsessed with finding Phineas Crane’s treasure, the most valuable and sought after by all the pirates of the Caribbean. To achieve this, he will need the help of Sparks, a girl who pretends to be a boy in order to survive among the savage members of the Barracuda crew. Finding a Phineas Crane memoir will be the key to reaching the long-awaited treasure and also Sparks’ lifeline, since she is the only one who can read on the ship and, therefore, the only one capable of deciphering that “Letter map” that the found manuscript supposes.
