Amazon's Prime Video has revealed that "Young Sherlock," starring Hero Fiennes Tiffin as a teenage version of the iconic detective, will premiere on Wednesday, March 4, with all eight episodes available at once. The series, executive produced by Guy Ritchie, explores the early adventures of Sherlock Holmes in 1870s Oxford. A new trailer highlights his arrival at school, a break-in investigation, fistfights, and an unlikely friendship with James Moriarty.
The announcement comes as Prime Video builds anticipation for the action-packed drama, which draws from the Sherlock Holmes legacy that Ritchie previously brought to the big screen in films starring Robert Downey Jr.
In the trailer, Fiennes Tiffin's Sherlock bids farewell to his mother, played by Natascha McElhone, promising to avoid trouble at Oxford. That vow quickly unravels as he dives into a school break-in probe, engages in intense brawls, and forms a bond with Dónal Finn's James Moriarty—a connection unlikely to endure given their canonical rivalry.
The official synopsis details how Sherlock "finds himself wrapped up in a murder case that threatens his liberty." This inaugural investigation uncovers a globe-trotting conspiracy that alters his life, set against the backdrop of 1870s Oxford and international escapades, revealing the anarchic youth who would later become Baker Street's famed resident.
Joining Fiennes Tiffin and Finn are Zine Tseng, Joseph Fiennes, Max Irons, and Colin Firth, adding depth to the ensemble. The series marks Ritchie's return to the Holmes universe in a television format, promising a blend of mystery, action, and coming-of-age elements.
Fans of the detective genre can expect the full season to drop simultaneously, allowing binge-watching from the premiere date.
