Spiral (2021) Ending Explanation

The film begins with a policeman named Marv Boswick walking through the street festival. He was robbed and went through the crowd to chase the perpetrator and follow him to the sewer system.

Later, Boswick was attacked by a man wearing a pig mask and was knocked unconscious. When he woke up, Boswick found himself on the subway track. He was standing on a stool, tied with a barbed wire, his tongue was screwed in with pliers. A television set on the track was turned on, and someone was seen imitating a video of the Jigsaw killer in the “Cry Saw” movie. The video said that Boswick used his tongue to lie to innocent people in court and on the railway.

Now, unless you stick out your tongue and jump out of the track, you will be run over by an approaching meteor. Boswick struggled and finally tore off his tongue. But it was futile because it was too slow and was crushed by the train.

We cut down a man named Zeke Banks (Chris Rock) who robbed with his gang. When his gang tried to escape, they were surrounded by police. Banks was revealed to be an undercover agent. Because he did not notify his police station of the robbery, his cover was blown up. Banks have no choice but to return to his detective role. The captain, Marisol Nichols, assigned him a rookie partner named Max Minghella.

Banks have strained relations with other police officers in the jurisdiction. Schenk learned that he was despised because he had turned in a dirty cop. Banks also feels inferior, because his father Marcus (Samuel Jackson) is the former district campus and a beloved cop. Schenk commented that Marcus was the reason for everything he did.

Banks and Schenk investigate the murder on the tube but do not know that the body is Boswick. The two were also very close. Banks told Schenk that he was divorced and did not trust women. Schenk replied that he and a young son were happily married.


After returning to the jurisdiction, Banks received a package with a USB flash drive. One of the messages was explained by Jigsaw’s new assassin. The murderer used a pig puppet in a police uniform as his avatar. The murderer explained that he intends to reform the police through his actions. It ends with a spiral image painted on the wall of the court.

The police went to the court, where they found another box. Inside is the Boswick tongue and insignia. The police now know that the killer is targeting them and Boswick was killed in the tube. Banks paid tribute to Boswick’s widow and argued with his ex-wife, who was also there.

Banks went home at night, where his father was waiting for him. The relationship between the two is distant and strained. However, Marcus promised to help Banks deal with the case at dinner the next night.

In the flashback, we learn that the police officer who Banks was appointed because of his filth is named Pete. Banks witnessed Pete shooting and killing a potential witness in a murder case against the police. As a result of Banksy’s testimony, Pete went to jail for nine years.

The next morning, Detectives Klaus and Fitch (Richard Zepieri) used the video footage to identify the person Boswick was pursuing before he was killed. They decided not to tell Banks because they hated him. Fitch went to a warehouse where he believed the suspect lived, but no one was found there. Instead, he was knocked unconscious by a figure wearing a cloak. When he woke up, he found himself in a trap.

That night, Banks went to his father’s house to handle the case, only to find that his father was missing. The flashback shows that Marcus does not approve of Banks’ appeal to Pete, but still does his best to protect his son from the inevitable counterattack.

The next day, another package from Jigsaw’s killer was sent to Banks, revealing a new location. Police ventured there and found Fitch’s badge and his ten severed fingers. The flashback shows us what happened.

Fitch once shot and killed an innocent person after insulting him during a traffic stop. The puzzle killer put Fitch in a bathtub that slowly filled with water. At some point, the water will hit the bare wires and electrocute you. Each Fitch’s finger is connected to the winch by a cable, and every time Fitch bites into a mechanism, the winch will start.

The puzzle killer explained in the recording that Fitch used his fingers to kill people, so now he must tear them off to survive. The detective tried to break his finger, but like Boswick, he was not moving fast enough to escape death.

In another flashback, we also learned that Fitch refused to provide Banks with an endorsement because it was angry with Pete. As a result, Banks was shot while hunting down the suspect. Marcus slammed Fitch because of his disobedience but did not remove him from the army.

Banks and Schenk continued to investigate but found no clues. Banks decided to ask Pete, who now runs the former criminal rehabilitation team. Pete regretted killing the witness but was still dissatisfied with Banksy’s surrender. However, he has an alibi for the murder. At the same time, Marcus has not yet returned home.

The next day, Banks received another package. This is Schenk’s skin (Banks recognizes it because he has a tattoo on Schenk’s arm). In the recording, the killer said that he was under Banksy’s skin and that he would soon search for his head. There is also a clue related to Banks’ past. Banks was shocked by the death of his new partner

When Banks went to inform the Schenk family of his death, the police scanner announced that the puzzle killer had attacked an assaulted police officer. Banks rushed to the scene, and the police said he was cut by a man wearing a pig mask. Banks is confused because it does not match the trick of the puzzle killer.

In the end, he concluded that the attack was just to distract the police. He also realized that when the murderer said he was “sane,” he was referring to Chief Garza as the chief of police. Banks could not contact the boss and hurried back to the station.

At the same time, Garza received a text message telling her to obtain a document from the cold storage to help her resolve the Jigsaw case. This message lured her into an ambush, and the murderer stopped her and tied her in a trap.

The murderer’s recording explained that Garza turned a blind eye to the rampant corruption in his yard and must be punished. Tap his head lightly, and boiling wax drips on his face. You can disable the trap by hitting the neck with a blade and severing the spinal cord. Otherwise, the wax will make it silent forever. Garza was killed by wax, and Banks was too late to save her.

Banks blamed Pete for the murder, while another policeman blamed Marcus. Banks didn’t know what to do, because he didn’t know where his father was. But he followed his initial leadership and chased Pete. When he arrived at Pete’s workplace, the murderer knocked him unconscious.

We cut to the nearest past and saw Marcus found the killer’s headquarters. Marcus was attacked by an assassin, and after a skirmish, he was knocked down.

When Banks recovered, he was handcuffed to a hacksaw nearby. Banks saw a pin on the ground nearby and was about to chop off his hand. Use a pin to open the lock. Banks learned that he and the arrested Pete were locked in a room. A recording tells them that Pete’s life is in Banks’s hands.

Then start the crusher, and the glass bottles are sent to the machine through the conveyor belt. When the bottle was crushed, the pieces shot out of the crusher and fell on Pete’s back. Banks found the key to rescue Pete but was hit by the glass while trying to rescue him. Although Banks rescued Pete from the trap, Pete died from his injuries.

The door opened, and Banks went out looking for Schenk. It turns out that Schenck is Jigsaw’s new killer. We learned that Schenk was the son of a witness who murdered Pete. Banks made sure Schenk wasn’t killed after helping him hide after his father was shot.

Schenk explained that he forged his family so that people would not suspect that he was the murderer, and the tattooed skin was the skin of Boswick, who was tattooed after Boswick’s death. Schenk also explained that he was inspired by the original puzzle killer John Kramer on this mission.

Schenk tells Banks that he has his father (he stole Banks’ phone number and texted him the address of the ambush). Schenk then asked Banks to work with him on the task of killing the dirty police. Banks said he would join Schenck, but the murderer did not trust him. Schenk said Banks failed the first test while trying to save Pete. Now he will give Banks a second test to see if Banks is trustworthy.

Schenk called the police and reported a shooting at his location. He then led Banks into a room, Marcus was tied up with rafter cables, and handed Banks a pistol with a bullet. Schenk has been slowly draining Marcus’s blood.


The proof is that Banks can devise a mechanism to free his father. If he does, Schenk will escape through the hidden elevator because he knows that Banks is not an ally. Banks could also shoot Schenk and arrest him, but then he would have no bullets to release Marcus, and Marcus would die from excessive blood loss. Or Banks can escape with Schenck to prove his commitment and become Schenck’s partner.

Schenk explained that Marcus was punished because he was the boss of the reign of terror and allowed his police department to engage in various illegal acts in the name of cracking down on crime. When Schenk said it was all because of Marcus, he meant that Marcus was indirectly responsible for his father’s death. Marcus opposed this claim and claimed that his strategy had more advantages than disadvantages. At the same time, the police arrived and started running towards the warehouse.

Banks finally activated the mechanism to free his father with a bullet. Although Marcus was still attached to the cable, they placed him on the ground. When Schenk ran to the escape elevator, Banks pulled out the tube that drained Marcus’s blood. The banks managed to catch up with Schenk and the two fought.

The police rushed in. The wire suddenly kicks in again, manipulating Marcus like a puppet (the kind of puppet Schenck used to message as a puzzle killer). The cables made Marcus look like he was pointing a gun at the police. The banks left Schenk and tried to arrest the police, but opened fire. Marcus was killed in front of his son. When Banks screamed angrily, Schenk disappeared into his elevator with a smile on his face.

It appears Zeke has two options: kill Will or try to deceive Marcus by shooting the target.

Even if Zeke shoots Will and kills him, the SWAT team will still intervene, cut off the tripwire, and activate the puppet “threat,” killing Marcus.

Zeke knocks Marcus down if he succeeds. It is now up to him to completely undo the seatbelts and clamps on Marcus’s limbs and body so he can escape. He can go to Will to get his gun connected or he can let Marcus escape. Both choices will result in Marcus’ death. That may be what Will expected. It’s obvious that’s what happened.
