this i know: Sarah's Confession

A recluse emerges from the backwoods on the eve of his son's romantic, southern wedding. Dinner spirals into chaos when the self-proclaimed prophet announces he hears spiritual messages straight from God. The voices tell him to prepare the way for the end of the world. His disturbing words find foothold in undeniable facts as disbelief dissolves into terror. Those who gathered to celebrate are suddenly faced with an unthinkable dilemma. They must follow him into a remote, secret sanctuary, prepared exclusively survival... or they can die. As apocalyptic events begin to unfold, the ancient battle of darkness and light quickly becomes a modern reality.
