Young Sherlock OTT release date in India: When and where to watch Guy Ritchie directorial show. Check plot, cast and all you need to know

Prime Video is set to take viewers back to the earliest chapter of Sherlock Holmes’ life with Young Sherlock, a new British series that looks at the detective long before Baker Street and global fame. The show, directed and executive produced by Guy Ritchie, focuses on Sherlock’s teenage and early adult years and the experiences that slowly shape his sharp mind and restless personality.

Based on Andrew Lane’s Young Sherlock Holmes book series, the show blends mystery, personal struggle, and period drama, while placing a younger, rough-edged Sherlock at the centre of a dangerous case.

When and where to watch Young Sherlock in India

For Indian audiences, Young Sherlock will premiere on March 4, 2026. The series will stream exclusively on Amazon Prime Video. All eight episodes are scheduled to release together, making it a binge-ready launch. Viewers will need an active Prime Video subscription to watch the show online. The series is also part of Prime Video’s global rollout and will stream across more than 240 countries and territories.


Set mainly in Victorian England, the story introduces Sherlock Holmes as a 19-year-old Oxford University student. At this point, he is far from the confident detective people know. He is impulsive, still learning, and often reckless. His life takes a sharp turn when he is framed for a murder at the university, putting his freedom at risk.

To clear his name, Sherlock is forced to investigate the crime himself. What begins as a fight to prove his innocence slowly opens into something much larger. The case leads him into a wider conspiracy that stretches beyond England and pulls him across international locations. Along the way, the show tracks how his instincts develop, how he learns to observe people, and how difficult choices start shaping his moral compass.

The series also explores Sherlock’s early years before Oxford, including his childhood and teenage experiences, which play a role in how he acquires skills that later define him as a detective.

Cast and characters

Hero Fiennes Tiffin plays the young Sherlock Holmes. Known for the After film franchise, he steps into a very different role here, portraying Sherlock as raw, restless, and still figuring himself out. Max Irons appears as Mycroft Holmes, Sherlock’s older brother. Joseph Fiennes and Natascha McElhone play the Holmes parents.

The supporting cast includes Dónal Finn as James Moriarty, marking the first meeting between Sherlock and the man who will later become his greatest rival. Zine Tseng plays Princess Gulun Shou’an, while Colin Firth appears as Sir Bucephalus Hodge. Other cast members include Holly Cattle, James Sobol Kelly, and Numan Acar.

Young Sherlock is created by Matthew Parkhill, with Guy Ritchie directing the first two episodes and setting the tone for the series. Christopher Benstead has composed the background score, while cinematography is handled by Mark Pattern and Oliver Loncraine. Physical production is managed by Motive Pictures.
