Meanwhile, three women who have been friends since college—Trina, Abbey, and Jackie—prepare for an annual "mystery weekend" trip, where one of them arranges a getaway in a location unknown to the other two. Jackie, who lives in New York City, has planned a camping trip for them in the Deep Barons, a forested area in rural New Jersey. Trina, a glamorous model living in Los Angeles, and Abbey, who returned to Chicago after college to care for her ailing mother, travel to New Jersey, where Jackie picks them up. After stopping at a nearby store for supplies, they arrive at their destination and begin to camp. While in the woods, they begin to explore, sitting around the campfire telling stories and having fun by swimming and fishing. Unbeknownst to them, they are being stalked by Ike and Addley. In the middle of the night, Ike and Addley attack the women, binding and gagging them. The three are taken by Ike and Addley to a ramshackle home in the woods where they live with their unhinged mother, whom they impress by torturing people. The brothers tie the women to exercise equipment inside the home, but Jackie is swiftly selected by Mother to be the brothers' first victim and is taken outside. Addley rapes Jackie while Ike photographs it, and Mother looks on encouragingly.
