The struggle goes on in 21st-century London, as the updated team of Sherlock Holmes and Dr. Watson battle the worst that modern criminality has to offer, including a computer-saavy archvillain who wants to rule the world.
Benedict Cumberbatch (Star Trek Into Darkness, The Fifth Estate) stars as the world's foremost (only, really) consulting detective, with Martin Freeman (The Hobbit, The Office UK) as his loyal, if edgy, sidekick, Dr. John Watson and Andrew Scott (Lennon Naked) as the unassuming mastermind of evil, Jim Moriarty.
