A film cast arrives at a wrap party, but someone has dressed up as the slasher in the movie and begins to stage their own kill scenes. One by one, the cast disappears until the true nature of the evening is revealed.

The wealthy and religious Eden family make dreams come true for people in need. But dreams can often become nightmares.

As Alyssa and Karla try to escape from the church home that holds them captive, Karla is slaughtered by a vicious, semi-human creature. After Detective Kimball tracks down Alyssa at a rowdy biker bar, she tells Kimball that women inmates disappear every full moon, and shows him the silver bullets in her gun. Now the two must return to the halfway house to confront the priest and nuns—and the snarling, savage evil—that dwell within.
