The Possession of Hannah Grace (2018) is a chilling horror-thriller that revitalizes the exorcism subgenre with a stark, morgue-set premise. Directed by Diederik Van Rooijen, the film follows Megan Reed (Shay Mitchell), a former police officer grappling with trauma and addiction, who takes a desolate night shift job at a hospital morgue. Her attempt at a quiet recovery shatters when the disfigured body of Hannah Grace, a young woman who died during a failed exorcism, is delivered. The film masterfully builds tension as Megan witnesses increasingly violent and inexplicable events emanating from the cadaver, forcing her to confront both a supernatural evil and her own inner demons.

The film's greatest strength lies in its atmospheric execution. The sterile, claustrophobic setting of the morgue, lit by cold fluorescent lights and filled with the hum of refrigeration units, becomes a character in itself. Shay Mitchell delivers a compelling, physically demanding performance, portraying Megan's vulnerability and growing resilience with authenticity. While the plot follows familiar possession tropes, it distinguishes itself through its procedural, almost forensic approach to the supernatural horror, focusing on the systematic breakdown of security and sanity in an institutional setting.

Viewers should watch The Possession of Hannah Grace for its effective jump scares, sustained dread, and a strong central performance. It's a compact, 86-minute thrill ride that doesn't overstay its welcome, offering solid scares for fans of contained, location-based horror. The film serves as a tense exploration of grief, guilt, and survival, proving that sometimes the most terrifying battles occur in the quietest, most isolated places.
