Saw IV continues the twisted legacy of the notorious Jigsaw killer, delivering a dark and brutal extension of the franchise’s interconnected story. This chapter expands the mythology of John Kramer, revealing more about his past, motives, and the consequences of his ideology. Directed by Darren Lynn Bousman, the film dares to prove that Jigsaw’s death does not mean his games are over.
Detailed Summary
Opening: Jigsaw’s Autopsy
The movie opens with the gruesome autopsy of the late John Kramer (Jigsaw), confirming beyond question that he is truly dead. During the procedure, a wax-coated tape is discovered inside his stomach, addressed to Detective Hoffman. The message implies that Jigsaw’s work will continue even after death. This shocking twist sets a disturbing tone and sparks a major question: Who is continuing Jigsaw’s legacy?
The Kidnapping of Officer Rigg
Veteran SWAT officer Daniel Rigg is ambushed in his home and forced into a series of timed games. Unlike previous victims who suffer for their crimes, Rigg is being tested for his overwhelming desire to save others. Each trap challenges his moral boundaries, pushing him to understand Jigsaw’s philosophy: “You can’t save everyone.”
Rigg’s Moral Journey
Rigg faces a disturbing series of challenges, including:
- Forcing a woman to choose survival by mutilating herself;
- Confronting a man who abuses prostitutes;
- Witnessing life-or-death decisions he cannot intervene in.
The message is clear: Rigg’s obsession with saving others is destroying him, and Jigsaw believes people must be allowed to choose their fate.
FBI Investigation: The Puzzle Deepens
Agents Strahm and Perez investigate clues connected to Jigsaw’s past. They learn about his late wife, Jill Tuck, and witness how an incident at her clinic impacts John’s transformation into Jigsaw. This storyline provides key emotional context, portraying Kramer not as a madman, but as someone who believes he has a higher purpose.
Movie Ending
The climax reveals that Rigg’s entire test was designed to teach him restraint. He was supposed to wait the full 90 minutes before attempting a rescue. However, unable to let go of his savior complex, he breaks through the final door anyway, triggering the mechanism that kills Detective Eric Matthews, who was being held captive on an ice block trap.
Rigg’s mistake also indirectly causes the gun-trap to kill Agent Perez. At the moment Rigg enters the room, Detective Hoffman appears restrained, pretending to be another victim. When Matthews dies, Hoffman stands up, untouched. The terrifying reveal arrives:
Hoffman is Jigsaw’s accomplice.
As Rigg dies, Hoffman walks away and plays the tape found in John’s stomach. The message promises that the games will continue. The movie closes with a chilling reminder: Jigsaw’s plan didn’t die with him. It evolved.
Are There Post-Credits Scenes?
No post-credits scenes are included in Saw IV. The story ends on Hoffman’s reveal, intentionally leaving the audience in suspense without additional footage.

Film Music and Composer
The score was composed by Charlie Clouser, whose industrial, atmospheric style has become synonymous with the Saw series. His music amplifies the dread and underlines the emotional and psychological stakes behind every decision.
Filming Locations and Their Importance
- Toronto, Canada: Most of the film was shot in abandoned industrial buildings, chosen for their bleak, deteriorating atmosphere. The crumbling structures reflect both the moral decay of the characters and the cold logic behind Jigsaw’s philosophy.
- Hospital and clinic sets were carefully designed to contrast life-saving environments with death-driven choices, deepening Jigsaw’s tragic origin.
Awards and Nominations
While Saw IV was a box-office success, it mainly received recognition in horror communities rather than mainstream awards. It was nominated at several horror film festivals for makeup and special effects due to its distinctive trap designs.
Behind the Scenes Insights
- Tobin Bell recorded the autopsy scene for more than eight hours to make the corpse realistic.
- Darren Lynn Bousman initially didn’t want to direct another Saw film but changed his mind after reading Jigsaw’s expanded backstory.
- Charlie Clouser’s iconic music was often composed after scenes were shot, tailored precisely to their tension.
- Many trap props were fully functional (though safe), allowing actors to interact physically rather than rely solely on CGI.

- Jigsaw’s trap logic resembles Nietzschean ethics, pushing individuals to overcome their weaknesses through suffering.
- The film expands on backstory elements hinted at in the Saw comics and previous film scripts.
Alternate Endings and Deleted Scenes
- A longer alternate version of Jigsaw’s autopsy was filmed but cut for pacing.
- Several additional flashbacks involving Jill Tuck were trimmed to avoid revealing too much about her future role in later films.
- A deleted scene revealed more of Hoffman’s manipulation during Rigg’s test but was removed to preserve mystery for Saw V.
