After his wife's death in a freak accident, Reverend Graham Hess questions his faith and even leaves the church. Six months later, he discovers a gigantic crop circle in his yard. Similar events happen all over the world. Graham's children think it's aliens, his brother thinks it's pranksters, and Graham doesn't know what to think. As more and more strange events occur, he realizes something big is coming and it probably won't be friendly.—rmlohner
