ToggleDetailed Summary
The New Killer in Town
The film opens with the murder of a police officer in a gruesome trap at a carnival. The killer leaves spiral-shaped clues behind, hinting that someone is emulating the late Jigsaw Killer, but with a new purpose. Detective Zeke Banks (played by Chris Rock) is assigned the case, though most of his fellow officers resent him for exposing a corrupt colleague years earlier.
Zeke and His Father
Zeke’s father, Marcus Banks (Samuel L. Jackson), is a former police captain who once led the department with unquestioned authority. Their relationship is tense, shaped by distrust, duty, and Zeke’s lonely reputation within the force. Marcus seems to have answers, but refuses to share them, leaving Zeke isolated at a crucial time.
The Corruption Secret
As more officers fall victim to vicious traps, Zeke begins seeing a connection: the killer is targeting corrupt cops who have abused their power. This strikes a personal chord because Zeke has suffered professionally for refusing to support their cover-ups. The killer sends Zeke packages with grisly evidence, taunting him to “choose justice.”
The Rookie: Detective Schenk
Zeke works with his new partner, Detective William Schenk (Max Minghella). He appears inexperienced but enthusiastic, eager to learn from Zeke. He warns Zeke that exposing corruption makes him a target. This connection becomes critical later, as their partnership forms the emotional core of the plot.
Movie Ending
In the climax, Zeke discovers that Detective Schenk is the killer. His real name is Billy Emmerson, the son of a man killed by a corrupt cop years ago. The officer who committed the crime was protected by Zeke’s father and the entire department.
Billy reveals that he wants to work with Zeke, believing he shares his fight against police corruption. Billy even claims that he isn’t against law enforcement, only those who abuse power. His goal is to dismantle the system by punishing the corrupt under the same philosophy Jigsaw used: painful reform.
Billy places Marcus (Zeke’s father) in a final trap. Police bursts into the building, misinterpreting Marcus’s involuntary movements as a threat and instantly shoots him. As Marcus dies, Billy escapes, leaving Zeke torn between revenge, justice, and the system that just killed his father.
The movie ends with Billy getting away, while Zeke screams helplessly as the officers hold him back. The killer lives on, leaving the franchise open for continuation.
Are There Post-Credits Scenes?
There are no post-credits scenes in Spiral (2021). Once the screen cuts to black after Billy escapes, the story is over. The absence of a tease is deliberate, letting the unresolved ending linger.
