Sister Ann (Jacqueline Byers) answers the call to be the first female exorcist…but who or what appointed her? In response to the global increase in demonic possessions, Ann wants to enroll in an exorcism school reopened by the Catholic Church. Until now, these schools have only trained priests in the Rite of Exorcism – but a teacher (Colin Salmon) recognizes Sister Ann’s gifts and agrees to train her. Brought to the forefront alongside her colleague, Father Dante (Christian Navarro), Sister Ann fights to save the soul of a child she believes is possessed by the same demon that tormented her mother years ago. Determined to root out evil, Ann soon realizes that the Devil is manipulating her to do exactly what he wants.
