A young woman takes a vow to become a nun for the rest of her life. Now known
as “Sister Maria,” she settles in at the local monastery for her new life of
poverty, chastity and obedience. Maria soon discovers something horrifying
is happening within its locked gates… something beyond mere sin! The nuns are
being mercilessly tortured and when they try to flee, they suffer a worse fate!
After a brutal assault, Maria discovers she is now pregnant. Knowing it is
strictly forbidden for any nun to have relations with men, Maria must figure out
how to escape her own living Hell!
