what happens at the end of the shack
The Shack After spending the weekend at the shack, Mack leaves and is so preoccupied with his thoughts that he is nearly killed in an automobile accident. After his recovery, he realizes that he did not in fact spend the weekend at the shack, but that his accident occurred on the same day that he arrived at the shack. He also leads the police to the cave that Papa revealed, and they find Missy's body still lying there. With the help of forensic evidence discovered at the scene, the Little Ladykiller is arrested and put on trial.
Gerald's Game Jessie makes increasingly desperate attempts to escape, first by trying to break the headboard she is cuffed to, then by trying to slip off the bed and push it to the bureau where the keys are placed. One of the voices in her head tells her that if she stays another night, the Space Cowboy will take a part of her to add to its trophy "fishing creel" filled with jewelry and human bones. Jessie escapes the handcuffs by slicing her wrist open on a piece of broken glass, giving herself a degloving injury to lubricate her skin enough for the cuffs to slide off her right hand. She is then able to move behind the bed, push it to the bureau and use one of the keys to unlock her left handcuff. She passes out from blood loss. When she awakens, the Space Cowboy has made his way back into the house. Jessie confronts him and throws her wedding ring at his box of jewelry and bones, thinking that is what he wanted all along, then turns and runs out of the house. She makes it into her car and escapes the house, but is terrified to discover the Space Cowboy sitting in the back seat. Jessie crashes and is knocked unconscious.
