In the reversed scene, Detective Eric Matthew smashed his ankle with the water tank cover and escaped from the bathroom (the scene at the end of the second episode), had a fierce quarrel with Amanda, and was finally knocked down by Amanda. NS. Before Amanda left, Matthew left an angry curse, calling Amanda a "drug dealer's bitch", saying that she could not be a puzzle murderer, which made her very distressed. In the other inverted scenes, Amanda has been working with John (the puzzle murderer) from the beginning to kidnap Adam in accordance with his orders. But in fact, she suffocated Adam to death by euthanasia.
Detective Alison Kelly, Lieutenant Rigg, and Hoffman looked at Troy, the victim of the puzzle murderer, and found that his mechanism could not escape. Kelly was kidnapped when she went home. When she woke up, she found that she was in a mechanism. When she tried to escape using the provided method, Amanda appeared. Kelly realized that the mechanism was also unable to escape. After the mechanism was activated, Amanda appeared. She died.
At the same time, the dying jigsaw murderer ordered the kidnapping of two more victims: the highly skilled but melancholy physician Lynn Darren, and the father Jeff Reinhardt, who was determined to avenge his dead son. Amanda puts a collar on Linn's neck. There are five loaded bullet launching devices on the collar, which are connected to the puzzle murderer's electrocardiograph by radio. Lane's game rules are quite simple-keep John alive when Jeff completes the test. If she tries to escape the detection area or kills John, the collar on her neck will detonate. Jeff’s rule of the game is to save the other three objects he originally wanted to revenge from the organization, but his initial hesitation prevented everyone from leaving the organization and dying (although the benevolent judge was rescued, he was saving others. Accidentally touched the organ and died). After Jeff finished his experiment, he started looking for a puzzle murderer.
Lin succeeded in keeping John alive. John showed his love for his ex-wife Jill in the half-dream and half-awake period. Amanda mistakenly thought that John was confessing to Lin. She felt jealous and angry for a while and refused to obey his order to remove Lin's collar.

The Jigsaw Murderer only revealed the fact that Jeff and Lynn were husband and wife at the end.
Finally, John asked Jeff to forgive him and told Jeff that Jeff should be responsible for his son's death. Jeff hesitated a bit, hesitatingly said that he forgave John, but took a saw blade across John's throat. John recorded a tape with the details of Linn’s organization. He showed that he had successfully killed Lin. After that, Jeff discovered that his daughter was being locked in a room with insufficient air. He had to break through the barrier successfully. Find her. The door of the room was closed, the puzzle murderer died, and Lin died because of the detonation of the collar, and only Jeff shouted for help.
