The Possession of Hannah Grace (2018) is a chilling horror-thriller that delivers a tense, claustrophobic experience set in the unsettling environment of a hospital morgue. The film follows Megan Reed, a former police officer grappling with trauma and addiction, who takes a night shift job at a morgue to rebuild her life. Her routine is shattered when the disfigured body of Hannah Grace, a young woman who died during a failed exorcism, arrives. As Megan works alone through the night, she begins to witness increasingly violent and supernatural occurrences, realizing the corpse is far from dead and harbors a malevolent force.

Director Diederik Van Rooijen crafts an atmosphere thick with dread, using the morgue's sterile, confined spaces to amplify the sense of isolation and vulnerability. Shay Mitchell delivers a compelling performance as Megan, effectively portraying her resilience and unraveling sanity. The film's strength lies in its practical effects and jump scares that, while familiar to horror fans, are executed with precision to maintain suspense.

While the plot follows conventional possession tropes, it distinguishes itself through its unique morgue setting and the protagonist's personal struggle, which adds emotional weight to the supernatural terror. The brisk 86-minute runtime ensures a paced, engaging watch without unnecessary filler. For viewers seeking a straightforward, visually effective horror movie with solid performances and a consistently eerie ambiance, The Possession of Hannah Grace is worth watching for its effective scares and atmospheric tension.
