Abby (1974)

Living with her pious pastor husband, and her equally religious mother, the polite Christian marriage counsellor, Abby, is about to have a close encounter with the supernatural, when her archaeologist father-in-law, Bishop Garnet Williams, inadvertently unleashes an ancient spirit. Now, possessed with an unholy Nigerian deity, Abby becomes a violent, obscene, and sexually obsessed vessel of raw evil and nothing can stop her, or the entity that commands her. Can Williams expel the demon inside her?

Abby is a horror movie featuring Don Henderson and directed by William Girdler.
