NOT satisfying (possible spoilers)
A woman gives birth to an evil spawn, and dies. Another woman is chosen to uptake the spawn into her body, thereby to become its avatar. Consciously believing she is a nun, the child is programmed to fulfill a sinister prophecy driven by a renegade priest. Her father is helpless to protect her, but has a knowledgeable acquaintance who will go to great lengths to intervene on her behalf.
This is not a satisfying film. It consists of a confused plot that leads nowhere, and leaves you with an empty spot in your belly when it's all over. The acting isn't bad, but the script lacks soul.
