Ep 12. Captain Hardrock

In this episode of Miraculous, titled "Captain Hardrock," Ladybug and Cat Noir face a new villain - a pirate named Captain Hardrock. She is sailing around the Seine and attacking boats, stealing jewelry and priceless artifacts. The episode begins with a group of teenagers celebrating their friend Marlena's birthday on a boat on the Seine. Suddenly, Captain Hardrock shows up with her crew and starts attacking the boat. Ladybug and Cat Noir come to the rescue, but they are unable to stop Captain Hardrock from stealing a precious necklace.

After the attack, Ladybug and Cat Noir return to their civilian identities, Marinette and Adrien, and go to school. They discuss the situation with their classmates and try to come up with a plan to catch Captain Hardrock. Marinette suggests that they create a fake treasure to lure Captain Hardrock into a trap. They all agree, and begin to work on a plan to trap the pirate.

Meanwhile, Captain Hardrock decides to attack the Eiffel Tower. She wants to steal the metal and turn it into weapons. Ladybug and Cat Noir arrive on the scene and try to stop her, but she is too powerful for them. She uses her guitar to control the metal and create a powerful sonic wave that knocks Ladybug and Cat Noir off their feet. They fall into the Seine and are swept away by the current.

When they wake up, Ladybug and Cat Noir find themselves on a deserted island. They realize that Captain Hardrock has stranded them there and they need to find a way to escape. They explore the island and find a cave with a statue of a mysterious sea god. They also find a message in a bottle that gives them a clue to help them escape.

Back in Paris, Marinette's classmates have finished creating the fake treasure and are ready to lure Captain Hardrock into a trap. They place the treasure on a boat and sail it on the Seine, hoping that the pirate will take the bait. As expected, Captain Hardrock shows up and attacks the boat. However, she quickly realizes that it's a trap and throws the treasure overboard.

Ladybug and Cat Noir use the clue from the message in a bottle to locate a hidden passage in the cave. They follow the path and discover a hidden lair filled with treasure. They also find a map that shows the location of all the treasures that Captain Hardrock has stolen. They realize that they need to stop her before she can steal any more treasures.

Ladybug and Cat Noir return to Paris and join forces with Marinette's classmates to stop Captain Hardrock. They use the map to track her down and confront her on the Seine. Ladybug and Cat Noir work together to defeat her, using their powers to create a giant whirlpool. They manage to trap Captain Hardrock and her crew in the whirlpool, and recover all the stolen treasures.

In the end, Ladybug and Cat Noir return the treasures to their rightful owners. Marinette's classmates are happy to have helped, and everyone celebrates their victory over Captain Hardrock. As always, Ladybug and Cat Noir return to their normal lives, ready for their next adventure.
