By the seas, the court of Dona Emilia del Scuebo sails peacefully on the ship of the captain of La Loya. However, bad winds lead the unfortunate to cross the road of the crew of the dreaded Barracuda. The rich passengers are taken prisoner by the greedy pirates of Blackdog, their chief. The old captain, as violent as he is cunning, immediately becomes aware of the profit that he can draw from such prestigious prisoners. On the ill-fated island of Puerto Blanco, unsanitary den of the vermin of the seas, Blackdog coins at gold price the lives of Dona Scuebo, her daughter, the beautiful Maria, and their young valet, while focusing on his new project: to go in search of the treasure of the Scuebo. The destinies of some will then intersect around the same quest – the diamond of Kashar, jewel of the treasure of the Scuebo family.
