Inspired by the characters in Arthur Conan Doyle’s Sherlock Holmes mysteries, Watson is set six months after the death of Holmes, the title character’s friend and partner, at the hands of arch-villain Moriarty. It follows the detective as he shifts his focus from solving crimes to solving medical mysteries.

Chestnut stars as Dr. John Watson, who resumes his medical career as head of a clinic treating rare diseases. But Watson isn’t done with his old life yet—Moriarty and Watson are ready to write their own chapter in a story that has captivated audiences for over a century.

Eve Harlow, Peter Mark Kendall, Inga Schlingmann, Ritchie Coster, and Rochelle Aytes also star. Randall Park guest stars as Professor James Moriarty, alongside Matt Berry as the voice of Sherlock Holmes.

The first season will have a two-part finale on Sunday, May 4 and Sunday, May 11, making it a total of thirteen episodes.
