In this sequel, Enola Holmes (Millie Bobby Brown) has established herself as a private detective, determined to prove her skills and make a name for herself. Her latest case involves a missing girl named Bessie who has disappeared under mysterious circumstances.

As Enola investigates, she uncovers a complex conspiracy involving powerful figures and hidden agendas. Her search for Bessie leads her deeper into London’s underground world, where she encounters various challenges and dangerous situations.

Sherlock Holmes (Henry Cavill) also appears in the film, and his presence adds both assistance and tension to Enola’s investigation. The siblings’ dynamic is explored further as they work together, though Enola’s independence often clashes with Sherlock’s more conventional methods.
