Bleak House unfolds under the long shadow of the Jarndyce v Jarndyce case, a probate dispute that drags on for years and bleeds into the lives of everyone it touches. John Jarndyce [Denis Lawson] welcomes Ada Clare [Carey Mulligan] and Richard Carstone [Patrick Kennedy] as his wards, and he hires Esther Summerson [Anna Maxwell Martin] to be Ada’s housekeeper and companion. Lady Dedlock [Gillian Anderson], the wife of the formidable Sir Leicester Dedlock, also looms as a potential beneficiary, while the case itself seems to drain every other pursuit from the people drawn into its orbit. The Dedlocks’ lawyer, Tulkinghorn [Charles Dance], begins to sniff out a hidden thread tying Lady Dedlock to a recently dead man named Nemo, and as he pursues that mystery, Lady Dedlock herself quietly probes the past to uncover what she might have kept hidden. In the meantime, Richard and Ada find themselves drawn to one another, even as Richard vacillates over his future—doctor, lawyer, or soldier—as the lure of an inheritance gnaws at him. Esther starts to form a meaningful bond with Allan Woodcourt [Richard Harrington], a capable young doctor, but she battles a sense of unworthiness, and Allan eventually accepts a commission as a navy physician, pulling him away at a crucial moment.
The sharp-eyed Guppy [Burn Gorman], a law clerk who admires Esther, tries to win her affection by digging into the origins of her family. He uncovers connections to both Lady Dedlock and Nemo and learns of Hawdon’s letters, which are in the possession of a drunken landlord named Krook. When those letters surface, Esther’s parentage—touched by a past that Lady Dedlock has kept secret—starts to come into sharp relief. Lady Dedlock confesses her secret to Esther, but insists on secrecy to spare her daughter from harm. Esther endures a brutal bout of smallpox that leaves her scarred, yet she survives. John proposes marriage to Esther, but she agrees to delay, wanting to be certain of the life she chooses. Tulkinghorn’s relentless pursuit of the truth presses hard on Dedlock, hinting at danger if the secret is exposed.
Tragedy intensifies when Tulkinghorn is murdered, sending a shockwave through the house and leaving many as possible suspects. Though Lady Dedlock bears the weight of suspicion for a time, Inspector Bucket uncovers the real culprit: Hortense, Dedlock’s former maid, who had attempted to frame her mistress. Richard and Ada, secretly married, are pulled into the financial and moral strain of the case as Richard’s fixation on the lawsuit worsens his health and wealth. Hawdon’s letters—embodied in the actions of Smallweed, who buys and sells them—eventually circle back to Sir Leicester, piling pressure on the Dedlocks and threatening to unravel their past in public. In the midst of mounting tension, Lady Dedlock flees into a violent storm, and though Sir Leicester suffers a stroke, Bucket presses onward, tracing her path to the graveyard where Hawdon lies. Esther arrives to find her mother dead, a heartbreaking culmination of hidden truths and sacrificed reputations.
A final Jarndyce will emerges, and the long-running case ends in favor of Richard and Ada, yet the legal costs have already stripped the estate nearly bare. Richard collapses from tuberculosis and dies soon after, his dreams of a secure future left in ruins. Allan confesses his love for Esther, but she chooses to honor the memory of John and the life they could have shared. Ada, now pregnant, returns to Bleak House, and John releases Esther from their engagement, recognizing that her heart lies with Allan. In the end, Esther and Allan marry, surrounded by those who remained loyal through the ordeal, while Ada forges a new path toward the future. The story closes on a note of quiet resilience, with the characters' lives rebuilt from the wreckage of a case that, for so long, consumed everything in its wake.
