A bishop-archaeologist-lecturer Garnet Williams(William Marshall) excavates the cave during a digging expedition in Nigeria.Big mistake,because he releases Eshu,Nigerian demon of sexuality.Garnet's daughter-in-law Abby(Carol Speed)is possessed by the entity.Abby who is devoted Church goer begins acting oddly engaging in self-mutilation,verbal and physical abuse of her husband,mocking the Church and finally slutting herself over town.Vastly entertaining and very enjoyable "The Exorcist" clone with plenty of cheese and pulsating funk soundtrack.Overall,I think that "Abby" deserves to be seen and more appreciated,especially if you are into blacksploitation sub-genre.7 possessions out of 10.
