First trailer of 'Young Sherlock' brings action and mystery

And here’s the official synopsis for Young Sherlock from Prime Video:

With all the wit and charm of Guy Ritchie’s Sherlock Holmes feature films, Young Sherlock follows the origin story of Sir Arthur Conan Doyle’s beloved detective in an explosive re-imagining of this iconic character’s early days. Sherlock Holmes is a disgraced young man – raw and unfiltered – when he finds himself wrapped up in a murder case that threatens his liberty. His first ever case unravels a globe-trotting conspiracy that changes his life forever. Unfolding in 1870s Oxford and adventuring abroad, the series will expose the early antics of the anarchic adolescent who is yet to evolve into Baker Street’s most renowned resident.

Ritchie himself will direct the first two episodes of the 8-episode season. The series will also star iconic actors Joseph Fiennes and Colin Firth. Dónal Finn, Zine Tseng, Natascha McElhone, and Max Irons round out the cast. This isn’t the first “Young Sherlock Holmes” project ever made, of course. In 1985, there was a Young Sherlock Holmes movie, which didn’t exactly set the world on fire. Maybe this series will fare better with fans? The eight episodes of Young Sherlock will all drop on Prime Video on March 4, 2026.
