Pregnancy, birth, and postpartum recovery are challenging experiences that impact womens physical, mental, and emotional health in ways that have been historically minimalized, dismissed, or neglected. A mothers body becomes a public body, physically and politically not her own, instead shared by her spouse, her children, and those around her. Her body, therefore, makes the perfect vessel for an invasive presenceor possession. The Sinful Maternal: Motherhood in Possession Films examines the role of mothers and motherhood in ten possession films, including Rosemarys Baby, The Exorcist, The Babadook, and Hereditary. Chapters discuss the work of such directors as James Wan, Jennifer Kent, Robert Eggers, and Ari Aster to address how their cinematic approaches to these films produce rich possession narratives that explore different facets of motherhood and womens agency.

Working at the intersections of gender studies, architectural theory, trauma studies, and monster theory, with a particular focus on the treatment of (often unruly) female bodies, author Lauren Rocha investigates the ways in which motherhood is a fertile state for possession and how possession acts to influence, destabilize, and reshape identity and the self. Placing the films in chronological order, she closely analyzes the ways in which sociocultural influences create different roles women and mothers are expected to perform. Ultimately, Rocha demonstrates how possession offers a way to challenge performative motherhood to free the self.
