It’s October 31st and, as an alternative to Halloween, the kids are at a church retreat. Will Flo bag the hot, older counselor? Can Tad and Zeke put aside their friendly rivalry to help win the soccer game for their cabin? Does Max learn how to have a good time in the great outdoors? Is something really awful and violent and horrible and weird going to happen that derails all of this? (The answer to that last one is, “Yes.”)
