Sherlock Holmes is getting a serious glow-down — and Guy Ritchie is the one holding the camera. Prime Video has dropped the first trailer for Young Sherlock, an action-heavy origin story that reimagines the legendary detective as a rebellious teenager with a knack for trouble and a nose for conspiracy. Directed and executive produced by Guy Ritchie, the series promises a high-energy, stylized spin on one of fiction’s most iconic minds.

Leading the charge is Hero Fiennes Tiffin as a youthful Sherlock Holmes, long before Baker Street, the deerstalker, and the pipe. This young whippersnapper is sharp, charismatic, and more than a little reckless — traits that land him in the middle of his first major case when he crosses paths with none other than James Moriarty. When the series was announced, it was teased with the following:

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.
