The sequel picks up where the storyline from the original film – released last year, and based on the much-loved books by Nancy Springer – left off.

The trailer opens with Enola doing what she knows best: outrunning the chaos and uncontrollable adventure that seems to follow her everywhere she goes.

Enola has grown up since we last saw her, and is now running her own detective agency fresh off the triumph of solving her first case, following in the footsteps of her older brother, Sherlock. But not everyone is convinced. As she deals with a stream of disbelieving and doubtful clients who would appear to prefer the investigative assistance of her more famous brother, Enola is frustrated and now without a case to her name.

But it’s not all smooth sailing for Henry Cavill’s Sherlock, either. Stumped by his latest mystery and seemingly driven to disillusion, Enola is not only left to deal with her own struggling business but her brother’s descent into despair, too.
