The episode begins with the TARDIS materializing on a deserted 17th-century pirate ship, the "Mary Rose." The Doctor, Amy, and Rory step out to explore the ship, which is eerily quiet. They soon discover that the crew is missing, and the ship appears to be adrift in a thick fog. As they investigate, they find a strange black spot on the ship's deck, which seems to pulse ominously.

Suddenly, a crew member named the Captain, who is visibly distressed, appears. He reveals that his crew has been disappearing one by one, taken by a mysterious force. The Doctor, intrigued, begins to analyze the situation, while Amy and Rory try to comfort the frightened Captain. The tension rises as the crew member, a man named Toby, is suddenly struck by the black spot, which manifests as a glowing mark on his palm. The Captain panics, believing that the black spot is a curse that will lead to his crew's doom.

As the Doctor investigates further, he discovers that the ship is not just adrift but is also caught in a time loop. He realizes that the black spot is connected to a siren-like creature that is responsible for the crew's disappearances. The creature appears to be a manifestation of the ship's own fears and desires, drawing the crew members to it. The Doctor deduces that the creature is not malevolent but is instead trying to protect something.

The crew's situation worsens when another crew member, a young man named Jim, is also marked by the black spot. The Doctor, Amy, and Rory work together to devise a plan to confront the creature and save the crew. They gather the remaining crew members and prepare to face the siren. The Doctor uses his sonic screwdriver to try to communicate with the creature, hoping to understand its motives.

As the confrontation unfolds, the siren appears, a beautiful yet terrifying figure, and begins to lure the crew members towards her. The Doctor realizes that the creature is not just a monster but is actually a form of a medical hologram, programmed to protect the crew from a deadly disease. The crew members are drawn to the siren because they are subconsciously seeking help from her.

In a climactic moment, the Doctor confronts the siren, explaining that she is misinterpreting the crew's fear and desire for survival. He urges her to let the crew go, revealing that they are not in danger from her but from the disease that she is trying to protect them from. The siren hesitates, torn between her programming and the Doctor's words.

Meanwhile, Amy and Rory work to keep the crew members safe from the siren's pull. They manage to break the spell of the black spot on Jim, but the Captain is still in danger. The Doctor, using his quick thinking, devises a plan to reverse the siren's programming. He instructs the crew to focus on their memories and their will to survive, which helps to weaken the siren's hold on them.

In the final moments, the Doctor successfully convinces the siren to release the crew, and she dissipates into a cloud of shimmering light. The crew members are freed from the curse of the black spot, and the ship begins to stabilize. The Doctor, Amy, and Rory prepare to leave, having saved the crew from their fate.

As they depart, the Captain expresses his gratitude, and the Doctor reflects on the nature of fear and the importance of understanding one's own desires. The TARDIS dematerializes, leaving the crew of the Mary Rose behind, safe and sound. The episode concludes with the Doctor, Amy, and Rory stepping back into the TARDIS, ready for their next adventure.

At the end of "The Curse of the Black Spot," the Doctor, Amy, and Rory manage to save the crew of the pirate ship, the Fancy, from the Siren, a creature that has been attacking them. The Doctor discovers that the Siren is a holographic projection created to protect a dying boy, and he successfully negotiates a resolution. The crew is freed, and the Siren is no longer a threat. The episode concludes with the Doctor, Amy, and Rory leaving the pirate ship, having resolved the conflict.

As the episode nears its conclusion, the tension aboard the Fancy escalates. The Doctor, Amy, and Rory have been navigating the dangers of the ship, which is haunted by the Siren, a mysterious entity that marks its victims with a black spot before claiming them. The crew is terrified, and the atmosphere is thick with fear and desperation.

Scene by scene, the Doctor confronts the Siren, realizing that it is not a malevolent force but rather a guardian of a young boy named Toby, who is gravely ill. The Siren's actions stem from a protective instinct, as it seeks to save Toby from the pain of his condition. The Doctor, with his characteristic empathy and intelligence, devises a plan to communicate with the Siren, understanding that it is not the enemy but a misunderstood protector.

In a pivotal moment, the Doctor uses the ship's technology to project a message to the Siren, explaining that it does not need to harm the crew to protect Toby. The emotional weight of the scene is palpable as the Doctor appeals to the Siren's sense of duty and compassion. The crew watches in awe as the Doctor's words resonate with the Siren, leading to a moment of clarity.

As the Siren begins to understand, the tension dissipates. The crew, who had been on the brink of despair, now sees a glimmer of hope. The Doctor assures them that they will be safe, and the Siren, in a moment of vulnerability, reveals its true form--a holographic projection that fades away, leaving behind the boy Toby, who is now free from the Siren's grasp.

In the aftermath, the crew of the Fancy is relieved and grateful. They express their thanks to the Doctor, Amy, and Rory, who have not only saved their lives but also brought peace to the situation. The Doctor, with his usual charm, bids farewell to the crew, leaving them with a sense of hope and a renewed perspective on their lives.
