Sherlock & Daughter, Season 1, begins with Sherlock Holmes in a state of extortion, unable to investigate a series of high-profile kidnappings, including that of an ambassador's daughter, Clara Anderson. Sherlock is sidelined by threats from the criminal syndicate known as the Red Thread, who have kidnapped his closest friends and sent him a severed finger as a warning. Into this tense situation arrives Amelia Rojas, a young Native American woman from California whose mother was recently murdered. Amelia comes to London seeking Sherlock, hoping he might be her biological father and to find justice for her mother. Sherlock reluctantly accepts her presence but remains cautious due to the danger posed by the Red Thread.

In the first episode, "The Challenge," Sherlock is blackmailed and prevented from investigating the kidnappings himself. Amelia arrives at 221B Baker Street and quickly becomes involved in the case. Sherlock sends her on a mission to follow the trail of the kidnappers, hoping she can operate undetected. Amelia's investigation leads her across London, where she follows her intuition and uncovers clues that bring her closer to the kidnappers but also into increasing danger.

In episode two, "The Common Thread," Sherlock pursues a stolen carriage linked to the kidnappers while Amelia continues her independent investigation. She tracks leads through London's streets, demonstrating resourcefulness and determination. Meanwhile, Sherlock investigates the role of the newfangled telephone technology in the Red Thread's operations, suspecting it is a key tool for their criminal activities.

Episode three, "Partners in Crime," sees Amelia going undercover at Clara Anderson's home to search for clues. Sherlock, meanwhile, visits Newgate Prison under the pretense of meeting his arch-enemy, Professor James Moriarty, who is incarcerated there. This visit is part of Sherlock's strategy to gather intelligence on the Red Thread and their connections. Amelia's undercover work reveals important information but also exposes her to significant risk.

In episode four, "For Kith and Kin," Amelia encounters a charming man armed with a pistol during her investigation. She withholds this information from Sherlock, fearing the implications. Sherlock, however, must intervene when Amelia's investigation takes a deadly turn. The episode culminates in a tense confrontation where Sherlock races to Amelia's side, arriving just as the situation becomes fatal. This sequence involves a step-by-step escalation from Amelia's initial contact with the man, through her growing suspicion, to the violent climax that forces Sherlock to act decisively to protect her.

Episode five, "Doubting Thomas," focuses on Sherlock's search for missing jewels connected to the kidnappings of his friends. He enlists the help of Birtwistle, a brash insurance investigator eager to assist. Sherlock, determined to keep Amelia safe or perhaps at a distance, assigns her to undercover work away from direct danger. Amelia chafes at this sidelining, forced to endure tedious dance lessons and the cutting remarks of Lady Violet Somerset, a wealthy socialite who trains young women in proper etiquette. Despite her frustration, Amelia's assignment leads to revelations about the social dangers lurking within high society, particularly at debutante balls, which become a critical setting for uncovering further clues.

Throughout the season, Sherlock and Amelia's partnership deepens as they navigate the perilous investigation into the Red Thread syndicate. Sherlock's investigation into the telephone's role in the criminal network and Amelia's undercover missions converge, leading to deadly consequences. The season ends with unresolved tensions and the looming threat of the Red Thread, setting the stage for further developments.

Key character decisions driving the plot include Sherlock's reluctant acceptance of Amelia's involvement, his strategic use of undercover work to protect her, Amelia's independent and intuitive investigative approach, and Sherlock's engagement with his nemesis Moriarty to gain insight into the criminal syndicate. The season is marked by escalating danger, with kidnappings, confrontations, and the constant threat of violence shaping the narrative progression.

The season 1 finale of Sherlock & Daughter ends with Sherlock Holmes and Amelia Rojas confronting the Red Thread syndicate at a high-society debutante ball. Amelia kills Lady Violet, the syndicate's fanatic leader who had murdered Amelia's mother, while Sherlock stops an assassination attempt on the Prime Minister. The gold stolen from the Bank of England is recovered, the conspirators are exposed, and the fate of the main characters is revealed.

Expanding on the ending scene by scene:

The finale opens with Sherlock revealing to Amelia that he and her mother had been lovers, but her mother left without telling him she was pregnant. This personal revelation sets the emotional tone for the climax.

At the debutante ball, the most anticipated social event of the season, Sherlock and Amelia prepare to confront the Red Thread syndicate, who have orchestrated a complex plot involving the theft of gold from the Bank of England and the kidnapping of their friends, including Dr. John Watson and Mrs. Hudson.

Sherlock and Amelia uncover that the theft was a scheme to crash the bank's value, allowing syndicate members like Anderson to buy shares cheaply and profit massively when the gold was recovered. Anderson made $10 million from this manipulation. They also learn that Inspector Whitlock was corrupt and aiding the syndicate.

Amelia and Clara overhear a conversation revealing Lady Violet as the true mastermind behind the Red Thread. Violet is fanatical and had killed Amelia's mother to obtain her weapon plans, which Violet intended to sell.

During the ball, Amelia confronts Lady Violet. In a tense and decisive moment, Amelia outsmarts and kills Violet, ending her reign of terror.

Meanwhile, Sherlock prevents Herbert, a syndicate assassin, from killing the Prime Minister, Lord Salisbury, thwarting the final part of the Red Thread's plan to destabilize the government.

The stolen gold is recovered, Watson and Mrs. Hudson are rescued, and the syndicate's plot is fully exposed. Anderson's betrayal is revealed, and he faces consequences for his role.

The episode closes with Watson finishing writing the case titled "The Case of the Red Thread," and Sherlock sending the manuscript off, signaling the end of this chapter but hinting at future adventures.
