Tomas and Simon have always loved spending weekend's at their grandparent's house. But when the boys' parents become born-again Christians, they insist that Grandma and Grandpa find a church home as well, or the boys can't stay the weekend. They find a church, but as Simon and Tomas soon discover, it's anything but ordinary. In fact, it's unlike any church they've ever seen. Shifty eyes and hushed conversations are just the beginning. Something ominous lurks behind a closed door. Hell, in more ways than one, is about to break loose.
