Subtitled Angels of Death, ShockTillYouDrop.com has revealed a synopsis for the follow-up to the Daniel Radcliffe-starring horror movie.
"Seized by the government and converted into a military mental hospital during World War II, the sudden arrival of disturbed soldiers to Eel Marsh House has awoken its darkest inhabitant," it reads.
"Eve, a beautiful young nurse, is sent to the house to care for the patients, but soon realises she must save them from more than their own demons. Despite Eve's efforts to stop her, one by one they fall victim to the Woman in Black."
The sequel was confirmed in April, with story editor Jon Croker returning to adapt an original story by Woman in Black writer Susan Hill.
The Woman in Black became the UK's most successful horror film in 20 years when it was released earlier this year.
A director is yet to be announced for The Woman in Black: Angels of Death.
