A new game is afoot!

The trailer for Netflix’s new Sherlock Holmes spinoff “Enola Holmes” has dropped.

The film stars Millie Bobby Brown as the teenage sister of legendary sleuth Sherlock Holmes. The film will be directed by “Fleabag” director Harry Bradbeer.

The trailer features plenty of action, intrigue, and humour as the “Stranger Things” star traipses through Victorian England on the search for her mother.

Netflix first released a teaser and photos earlier in August with an official synopsis.

“England, 1884 — a world on the brink of change,” states Netflix’s synopsis for the movie, based on the book series by Nancy Springer.

“On the morning of her 16th birthday, Enola Holmes (Millie Bobby Brown) wakes to find that her mother (Helena Bonham Carter) has disappeared, leaving behind an odd assortment of gifts but no apparent clue as to where she’s gone or why,” the synopsis continues.

“After a free-spirited childhood, Enola suddenly finds herself under the care of her brothers Sherlock (Henry Cavill) and Mycroft (Sam Claflin), both set on sending her away to a finishing school for ‘proper’ young ladies. Refusing to follow their wishes, Enola escapes to search for her mother in London,” the synopsis adds.

“But when her journey finds her entangled in a mystery surrounding a young runaway Lord (Louis Partridge), Enola becomes a super-sleuth in her own right, outwitting her famous brother as she unravels a conspiracy that threatens to set back the course of history,” concludes the synopsis of “a dynamic new mystery-adventure that introduces the world’s greatest detective to his fiercest competition yet: his teenage sister. The game is afoot.”
