A mysterious group known as "The Twelve" makes war with the Grigori...fallen angels who walk the earth. House of Fallen is loosely based on the Book of Enoch.
This was definitely not the worst teens in a haunted house movie I have ever seen. The acting was so so the actors were the typical obnoxious characters where you almost cant wait for them to die. The haunted house set was actually pretty good but I couldn't get past the plot or the story.
