The terrifying new trailer for “The Possession of Hannah Grace” has been unveiled ahead of its Nov. 30 release date.

Shay Mitchell stars as morgue-worker Megan Reed in the upcoming flick, which was originally titled “Cadaver”.

Kirby Johnson takes on the role of the corpse Hannah Grace, who is thought to have died when her family were performing an exorcism on her.

Hannah is said to have been killed in the middle of the procedure, with Meghan being told in the trailer, “You know what they say, when an exorcism is incompleted, evil will find a new vessel.”

However, Mitchell’s character insists: “I believe when you die, you die.”

She soon changes her mind when Hannah’s body ends up moving and coming to life during her night shifts.

A synopsis for the eagerly anticipated film reads: “When a cop who is just out of rehab takes the graveyard shift in a city hospital morgue, she faces a series of bizarre, violent events caused by an evil entity in one of the corpses.”
