What Happens in Sherlock Holmes: Full Plot Summary

The whole story of Sherlock Holmes (2009) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

The film opens with the iconic logos of Warner Brothers and Village Roadshow set into a cobblestone path, leading us into the nocturnal escapades of Dr. John Watson, portrayed by Jude Law, and Inspector Lestrade, played by Eddie Marsan, as they traverse the dimly lit streets in a carriage. Hot on their trail is the ever-energetic Sherlock Holmes, brought to life by Robert Downey Jr., who races through the shadows, skillfully maneuvering around columns and staircases before arriving at a nondescript building.

Inside, Holmes quickly descends into the depths of the structure, but he halts when he spots a henchman on guard, illuminated by a lantern. A swift analysis of the situation ensues, culminating in a carefully orchestrated attack — first rehearsed in Holmes's mind and then executed with remarkable precision: a hammer blow, a silence, and a swift drag. Upon reaching the basement, Holmes discovers a harrowing black magic ritual in progress. A young woman in a white dress lies bound to a table, while a hooded figure, later revealed to be Lord Henry Blackwood, chanted ominously over her. With a well-timed intervention, Watson dispatches the guard sneaking up behind them, facilitating a gripping moment of camaraderie filled with witty banter that underscores their strong friendship. “You really should learn to remember the simple things," Watson teases, referring to Holmes's forgetfulness about his pistol and stove.

The first act concludes with a harried escape, as Holmes and Watson thwart the ritual, saving the girl just before disaster strikes. Their exploits garner them fame, leading into a three-month time jump where we find Watson at Baker Street contemplating a move and perhaps a romantic future. Gunfire interrupts this domestic scene, ushering us back to the chaotic world of Holmes. Addressing his melancholic boredom since the Blackwood case, Holmes engages in humorous exchanges with Watson and Mrs. Hudson, culminating in a dinner invitation that Watson reluctantly extends.

This dinner quickly spirals into disaster when Holmes's unfiltered observations alienate Mary Morstan, leading her to storm off. Later, an impromptu boxing match showcases Holmes's physical prowess as he overcomes an opponent while distracted by the alluring presence of Irene Adler, played by Rachel McAdams. Just as Holmes revels in his victory, Adler’s enigmatic exit stirs his curiosity, setting the stage for a chess match of wits between the two.

Meanwhile, the narrative intensifies as Blackwood, now seemingly resurrected, makes a desperate request to see Holmes, fuelling a sequence of events driven by intrigue, friendship, and the mystique of magic. Watson and Holmes delve deeper into the eerie occurrences surrounding Blackwood's fate, leading to revelations about the secret society to which Blackwood once belonged and their dark intentions.

As the investigation unfolds, a thrilling escape through London ensues, laden with comedic exchanges and intense confrontations that highlight Holmes's brilliance and his struggles with his own demons. The stakes rise as they uncover a conspiracy involving the highest echelons of society, culminating in heart-pounding action sequences that blend mystery with explosive energy.

Throughout their adventures, the bond between Holmes and Watson is explored through both heartfelt moments and competitive banter, solidifying their relationship as that of true friends navigating a world riddled with danger and deception. The film encapsulates their journey from the chaos of Blackwood’s machinations to solving the cases that entangle their lives, ultimately culminating in a confrontation with the enigmatic Professor Moriarty—an adversary as clever and determined as Holmes himself.

In this captivating journey, themes of loyalty, intellect, and romance intertwine, culminating in a dazzling blend of mystery, action, and character development that leaves audiences eagerly anticipating the next escapade of these legendary figures.

Q1

Why does Lord Blackwood appear to be resurrected after Holmes defeated him?

She represents a rare intellectual challenge and operates outside conventional social boundaries as a professional criminal.
