Lucy, a study from home medical student and sleep paralysis victim, moves in with her boyfriend and finds out all is not as it seems, when she falls prey to a demonic force hell bent on ripping her apart from within. Torn between sanity and the unknown, Lucy is left with no alternative but to contact a local priest, Father Roberts for help. With time running out and the dark force consuming her from inside, Father Roberts is forced to make a choice, do the right thing and get the church involved, or help Lucy by conducting his own exorcism against the will of the church.
