Prime Video has released the first trailer of its upcoming series Young Sherlock, offering a fresh and action-packed look at the early life of legendary detective Sherlock Holmes.

The series stars Hero Fiennes Tiffin in the lead role, portraying a 19-year-old Sherlock Holmes during his student days at Oxford in the 1870s. Unlike the calm and methodical detective audiences know, this younger version is shown as impulsive, rebellious and sharp-minded.

The trailer suggests that Sherlock’s first major case begins after he crosses paths with James Moriarty, a meeting that sparks a rivalry shaping his future. According to the official synopsis, Sherlock is drawn into a murder investigation that threatens his freedom and leads him into a globe-spanning conspiracy. The story builds toward a dramatic confrontation that changes his life forever.

Set in Victorian England and across international locations, the series explores the early adventures of the anarchic teenager before he becomes the famed resident of Baker Street.

The eight-episode series is directed and executive produced by Guy Ritchie, who also directs the first two episodes. It is described as a fast-paced mystery tracing the origin story of the world’s most famous detective.

Young Sherlock will premiere exclusively on Prime Video on March 4, 2026, in more than 240 countries and territories.

The ensemble cast includes Zine Tseng, Joseph Fiennes, Natascha McElhone, Max Irons and Colin Firth. The series is created for television by showrunner Matthew Parkhill, with multiple executive producers attached.
