About the film
Contains story spoilers.
Sherlock Holmes begins this case with a warning disguised as a rescue. He intercepts a bomb intended for Dr. Hoffmanstahl and Irene Adler, then tells Irene that Moriarty is behind the attack. Moriarty’s people kill both targets, leaving Holmes to connect apparently separate murders, terrorist incidents and business acquisitions. His deductions suggest more than a criminal protecting a market: the professor is using violence to gain control of companies that stand to profit from war. Holmes is certain of the pattern, but his evidence is incomplete, and Moriarty understands that Watson’s approaching marriage is the detective’s most obvious vulnerability.
The celebrations around Watson’s marriage bring Holmes into the company of his brother Mycroft and introduces Madame Simza Heron, a Romani fortune-teller who is searching for her brother René. Holmes has taken a letter meant for Simza and saved her from an assassin, but she distrusts his motives and flees. After the ceremony, Holmes confronts Moriarty, who taunts him about Irene and threatens Mary and Watson. The threat becomes immediate on the newlyweds’ train journey: Moriarty’s men attack, and Holmes throws Mary from the train into a river so Mycroft can rescue her. Holmes and Watson fight off their attackers, but Watson’s honeymoon has become another pursuit across Europe.
In Paris, Simza agrees to help after Holmes explains that René may be involved in Moriarty’s plans. They visit the anarchist group she and her brother belonged to, whose members are being forced to plant bombs. Holmes deduces that the next device is at the opera, but it is actually in a nearby hotel, where an explosion kills businessmen and conceals the assassination of Alfred Meinhard by Moriarty’s sharpshooter, Sebastian Moran. Meinhard’s death gives Moriarty control of an arms factory. The detective has found the pattern but keeps arriving one step behind, as each apparently political attack doubles as a business transaction.
The trail leads to Germany and the factory, where Moriarty captures and tortures Holmes while Watson fights Moran in a watchtower. Holmes explains that Moriarty has bought shares in several war-related firms and is trying to trigger a European conflict that would make him immensely wealthy. Watson brings down Moran’s tower with a cannon, collapsing it into the factory and helping Holmes and Simza escape. Holmes then predicts that Moriarty’s decisive move will come at an international peace summit in Switzerland. The race changes from preventing individual bombings to identifying the person who can turn a diplomatic gathering into an international incident.
At the summit, Holmes recognizes René disguised as an ambassador. Hoffmanstahl had given him reconstructive surgery, allowing the assassin to move through the conference without being identified. Watson and Simza stop René’s attempt, but Moran kills him. Moriarty remains composed because he believes Europe will go to war eventually, regardless of this failure. Holmes reveals that he switched the professor’s diary while being held at the factory; the original contains the financial records and code that expose Moriarty’s holdings. Mary deciphers it and passes the information to Lestrade, who seizes the assets and directs the fortune toward war widows and orphans.
The investigation ends on a balcony beside the Reichenbach Falls. Holmes and Moriarty play chess while discussing the result of their contest, each aware that Holmes’s injured shoulder gives the professor an advantage in a physical fight. When Moriarty threatens Watson and Mary, Holmes chooses to take him over the railing. Watson arrives too late to stop them from falling. The subsequent funeral appears to confirm Holmes’s death, but the breathing device Mycroft had brought to the summit reaches Watson in a package. Watson recognizes the possibility that Holmes survived; meanwhile, Holmes is concealed nearby, reading Watson’s memoir and adding a question mark after its final words.
Guy Ritchie’s film sets deduction beside kinetic action rather than treating them as opposing modes. Holmes mentally rehearses likely movements before fights, and the movie renders those imagined outcomes as rapidly shifting possibilities before returning to the action actually chosen. The contrast lets a gunshot, a train carriage or a factory machine become both a physical hazard and a problem Holmes is solving. Philippe Rousselot’s cinematography moves from crowded interiors to wooded landscapes and industrial spaces, while Hans Zimmer’s score gives the chase its momentum. Robert Downey Jr. and Jude Law keep the partnership at the centre: Watson’s marriage changes his commitments, but Holmes’s final choice shows that the detective’s attachment to him is more than a convenient weakness. The escape through the forest makes the limits of prediction especially visible. Tree trunks and running bodies interrupt clear sightlines while artillery turns distance into danger; analysing a situation cannot make the wounded Holmes physically unharmed. Jared Harris gives Moriarty a controlled manner suited to someone who sees violence as an instrument of business. The contrast with Holmes’s restless improvisation makes their contest feel personal even when its consequences extend far beyond either man.
