On her 18th birthday, Yolanda discovers the story of her father, the Black Corsair. Because of that, when she meets the man she must get married, a dominant man who wants to turn her into a trophy wife, she feels the urge to flee. Yolanda and her hamster Emilio arrive in Genoa and stow away on a boat heading to Maracaibo. During the trip, Yolanda saves the life of a dolphin, whom she calls Star, and, as a consequence, she and Emilio are discovered. They are about to kill her when Morgan, aboard the pirate ship "Lightning", boards the ship. During the battle, Emilio is thrown into the sea and Yolanda jumps into the water to save him. Meanwhile, Morgan takes over the ship, discovers that Yolanda was on board, and recovers the Black Stone, which Yolanda had lost. The dolphin helps Yolanda and Emilio reach the coast on the way to Maracaibo, but she does not know that the evil Wan Guld has been alerted and is waiting for her.

After rescuing Yolanda and Emilio, the dolphin Star takes them to the beach in Maracaibo, where Yolanda sets out to find the Pirates of Tortuga Island. While stealing some more suitable clothes, Yolanda is about to be captured by the soldiers, but manages to escape. Then she goes into a tavern, disguised as a boy. There, Yolanda meets the vile pirate Jon “Halitosis” Largo, who discovers her true identity. Yolanda fights bravely, but is captured by Largo, who hands her over to Captain Valera and Wan Guld. Upon discovering that she does not have the Black Stone, Wan Guld locks her in prison and announces her execution to set a trap for the other corsairs. Yolanda escapes from the cell, but, after a valiant battle, is once again cornered. Suddenly, Morgan and his men come to rescue her. Together they manage to defeat the soldiers and flee.

The Corsairs try to get to the port of Maracaibo to "borrow" a boat with which to approach their ship. On the way, they discover Captain Valera and Albert collecting taxes for the Governor. The Corsairs fight with the soldiers and escape with the taxes. When the Corsairs give the collection money to a monk to distribute to the poor, the soldiers catch up with them and begin to chase them down a dead end. Our heroes escape through an open door and arrive at the house of a judge where, in a few hours, a wedding is to be held. Yolanda has an idea: Carmaux will dress in the judge's robes and hold the ceremony. But during the improvised wedding, the true judge manages to escape and sounds the alarm. Our heroes are forced to flee once more. The Corsairs invent an explosive and end up trapped on the roof of a burning building.

Yolanda, the corsairs, and young Carlitos are trapped on a burning roof. They manage to escape passing to the adjoining roof by a tightrope, while Captain Valera and his men shoot them from below. Yolanda falls off the tightrope and ends up facing Valera alone. But the ghost of her father appears to help her. The other corsairs rescue Yolanda in a buggy and Valera and her men chase them throughout Maracaibo. But our heroes manage to escape again, thanks to the help of a handful of old men and the monk to whom they gave the money from the tax collection for the poor (in the previous episode). The corsairs manage to reach the port, where they "borrow" again a sailboat to reach their ship, the Ray, moored offshore. The corsairs discover that Carlitos is stowing away.

In their endeavor to discover the mysterious purpose of the "black rose", our Corsairs embark on a harrowing marine crusade. First, they must defeat Wan Guld and his pirates to prevent the sinister governor from sinking his ship and stealing the black stone. Then Yolanda makes a great discovery. Her dead father, the Black Corsair, appears to him thanks to the power of the black stone and tells him the true story of the death of the “Three Corsairs”. Yolanda finds out that she has to find the "green map" and the "red scepter" which, together with the "black stone", constitute the key to reaching the great treasure.

After being thrown overboard in the storm, Yolanda and Morgan find themselves alone on a remote island. Before they can plan the next step, a spear brushes past them and Yolanda begins to pursue the attacker. Our heroes meet a primitive tribe, led by an evil Shaman. A young indigenous woman is about to be sacrificed and handed over to the mystical “Great Bird”, a legendary creature that supposedly inhabits the island's volcano. Yolanda and Morgan rescue the girl, so the fierce bird-clad tribe begins to pursue them. At the same time, Carmaux (sad), Mako and Carlitos float adrift on the Lightning, torn by the storm, in search of their lost companions.

We pick up the story when a poisonous snake, thrown by the witch, head of the island's tribe, attacks Yolanda. While rescuing Yolanda, Morgan is bitten by the beast. The young indigenous woman (whom Yolanda and Morgan have saved from being thrown into the volcano as a sacrifice) returns and tells them that although the snake's venom is deadly, there is an antidote. This antidote, which they must prepare, consists of three ingredients: the shell of a giant egg hidden in a cave full of death traps, the fin of a monstrous fish that lives in the river and, finally, a feather of the Great Bird that it hides inside the fierce volcano. Not knowing for sure if the “Great Bird” really exists, Yolanda and Morgan set out on this dangerous search for the three ingredients.

Although Wan Guld believes Yolanda dead, she is alive and well. She and her companions dock at Isla Tortuga, the former headquarters of the Corsairs of the Coast. As her classmates enjoy a boisterous “welcome home” party, Yolanda visits her father's abandoned mansion for the first time. Her emotional visit ends up being dangerous since the ghosts of two sailors who served under her father's orders believe that she is an intruder and they engage her in a ghostly sword fight with possible deadly results ... until the Black Corsair appears and puts order. In a matter of seconds, because Wan Guld, with the help of Jon Largo, has attacked the harbor with his heavily armed ships.

After driving Wan Guld's fleet away from Turtle Island, Yolanda and the Corsairs set out in search of him. Your goal is to retrieve the Green Map, one of the three keys to discovering the Corsair Treasure, which Wan Guld stole from the Green Corsair many years ago.

Forced to abandon the Lingote on a makeshift raft, Yolanda and the Corsairs battle a storm, knowing that Carlitos, poisoned by a thrust from Wan Guld's sword, may not be able to last the night. Mako knows how to prepare an antidote with the deadly needlefish scrape, but when Yolanda tries to catch it she pricks herself with the poisonous spines and Mako is the only one left to prepare it. Enough to preserve Carlitos' life overnight, but not enough to heal him or help Yolanda.

Determined to recover the Black Stone and the Green Map, two of the pieces of the puzzle leading to the Lost Treasure of the Corsairs, Yolanda and the Corsairs follow the evil Wan Guld and his henchman, Valera, to the prosperous island of Santo Tomas. There they find out that Wan Guld is having a party to raise money for his favorite charity: his own person. It is a costume party where everyone wears masks. Along the way, our heroes "borrow" the costumes of some guests who are heading to the party, dress up in them, and get inside. The fun begins.

After recovering the Black Stone and the Green Map (two of the keys necessary to unravel the secret of the lost Treasure of the Corsairs), our heroes rush to the docks in search of a way to get off the island, but Valera and his soldiers, including Albert, catch up with them. The Corsairs, notably outnumbered, fight bravely. During the battle, Valera tries to shoot Yolanda in the back of her, but Albert, who is an honest man, saves her life. Thanks to the ingenuity of Carlitos, the Corsairs are victorious, but are forced to separate.

Yolanda, Emilio and Carmaux are trapped in a cave with a poisonous python. The situation seems insurmountable until Yolanda draws strength from the Spirit from her father, the Black Corsair. With the help of her cunning and skill, Yolanda defeats the mighty serpent. After a magical and emotional gesture of "thanks" to her father, our three heroes continue their dangerous excursion. Yolanda doesn't know, but Governor Wan Guld and Valera are hot on their heels.

In the middle of a stormy night, Yolanda, Emilio and Carmaux arrive at the Castle of Montelimar where they ask for asylum. Alina, the ghostly patroness of the Castle, warns them of the presence of ghosts and leads them through its sinister corridors to the room where the Red Corsair once slept. Yolanda immediately falls into a deep sleep, but Carmaux is drawn to the kitchen by a strong smell of food. Emilio wakes up, discovers that Carmaux has disappeared and runs to alert Yolanda.

Yolanda believes that the Red Scepter is part of the Treasury of the Marquis of Montelimar. She and her friends find a clue that leads to an old water mill. But Wan Guld has ambushed them on a creepy suspension bridge.

Yolanda and the Corsairs are walking through the jungle in search of the Glu Glu birds when they are surrounded by a group of natives who capture them. Their boss, Atzul, orders them to be taken to the village, while he addresses Wan Guld and urges him to take over the kingdom of Darein. He then reveals to him that he has captured Yolanda.

While Neala talks with Yolanda and the corsairs, Wan Guld takes the opportunity to capture her entire tribe. His plan is to offer them to her in exchange for the Red Scepter and the Black Stone. On her side, Atzul, the chief warrior of the tribe, proposes to use this "failure" of Neala in the protection of her tribe to subject her to a "trial by magic". To do this, he has given her a necklace with a spell that will prevent her from talking to her animal friends, so that the crocodiles can eat her and he will become the new king of the tribe.

In the midst of a tropical deluge, Wan Guld and his men chase Yolanda and the Corsairs down a wild jungle river. Although Neala and her animal friends manage to make the Corsairs survive the attack of hungry crocodiles, the deadly Cascade of Angels awaits them, as Wan Guld approaches from behind. Only the timely appearance of the Black Corsair allows our heroes to harness the natural power of magnetic repulsion to miraculously escape the danger of BOTH the waterfall AND Wan Guld's and live to continue the search for the Three Corsairs' Treasure.

Yolanda and company, while walking through the jungle, help a boy, apparently lost and hungry. However, the boy betrays her trust by stealing the Red Scepter and running away with it. The corsairs chase him to a three-masted sailing ship anchored on a river bank, where they are ambushed by his former avenger, Captain Jon Largo. His crew is made up of boys, apprentice pirates, whom she supposedly takes to join his family. But Jon has other plans for them.

With Albert's help, Yolanda and the Corsairs escape Wan Guld and his pirates and find themselves, along with Princess Neala, in the safe company of a village of friendly indigenous people. But, while the natives feed them and provide them with provisions for their journey to Treasure Island with the map, the stone and the scepter, problems begin to brew in the town. Natzul, the young hunter of the tribe, does not trust "outsiders" and fears they will bring violence to his peaceful village.

Yolanda and Morgan, buried up to their necks in the sand, are about to drown when Neala, using her powers with the animals, calls giant sea crabs to dig them up. Once Yolanda and Morgan are freed, they, Neala and Albert begin a dangerous journey through the jungle with the intention of warning Carmaux that Wan Guld, guided by Natzul, the hunter of the tribe, is about to launch an attack with cannons. on the peaceful natives to recover the black stone.

Now that Yolanda and her Corsairs have captured the evil Governor Wan Guld and Sergeant Valera and know where the fabulous Treasure of the Corsairs is located, they set out safely for Treasure Island. To celebrate, they decide to initiate Wan Guld and Valera as Pirates, and have them climb the rigging, scrub the decks, clean the windows, and cook and serve a sumptuous meal. But Wan Guld is reaching the limit of his patience.

Lost in the sea, Yolanda is found by a family of seals and a family of dolphins, more dead than alive. As she is torn between life and death, she has a premonitory dream in which her father, the Black Corsair, shows her what would happen if she died. She sees Wan Guld victorious, demanding the Corsair Treasure and murdering his friends. Yolanda's mother, Honorata, the Black Rose, also urges Yolanda to "fight for the good." Yolanda begins by struggling to survive.

Yolanda and her friends are sailing to Treasure Island when, suddenly, the Lightning is engulfed in a thick fog. They lose all reference points until a mysterious figure appears and offers to guide them when Wan Guld and his men attack the Lightning. During the fight, the ships are strongly drawn into a huge whirlpool and disappear under the water. Fortunately, the Lightning is spat out by the whirlpool and lands right in front of Alyn-Nyla.

Yolanda and the Corsairs have finally reached the island of Nyla, where the fabulous Treasure of the Corsairs is buried. But in what part of the island? As our heroes follow the directions on the Green Map, the long-dormant volcano suddenly comes to life in fury. However, not even an erupting volcano can stop Yolanda and the Corsairs from continuing their search for the Corsairs' Treasure. When our heroes discover where the treasure cave is located, a figure dressed in black appears before them.

Yolanda and the Corsairs open the chamber door and find the treasure scattered before their eyes. Inside the chamber, there is also the tomb of the Black Corsair, whose image tells Yolanda what the true treasure is...
