#M ANNOTATED LLM RESPONSE
To understand what "starts the plot in motion" in Irreversible (2002), one must distinguish between the narrative beginning (what the audience sees first) and the chronological beginning (the events that actually set the tragedy in motion).
Because the film is famously told in reverse chronological order, the plot "starts" with the consequence and ends with the cause.
1. The Narrative Start (As Presented to the Viewer)
The film opens with a sequence of chaotic, nauseating camera movements and low-frequency "infra-sound" designed to induce physical discomfort. The specific actions that initiate the viewing experience are:
- The Philosophical Prologue: Before the main action, the film begins with two men—one being the Butcher from Gaspar Noé's previous film I Stand Alone—sitting in a dark room discussing the nature of time and crime, establishing the theme: "Time destroys everything."
- The Raid on "The Rectum": The camera immediately plunges into a gay BDSM club called "The Rectum." We see Marcus (Vincent Cassel) and Pierre (Albert Dupontel) frantically searching for a man nicknamed "Le Ténia" (The Tapeworm).
- The Fire Extinguisher Murder: This narrative "start" culminates in a brutal confrontation. Marcus is overpowered and has his arm broken; Pierre then intervenes, seizing a fire extinguisher and bashing the head of a man he believes to be Le Ténia until it is completely caved in. (Crucially, it is later revealed they killed the wrong man while the real Le Ténia watched from the shadows).
2. The Chronological Start (The Root of the Conflict)
If the film is viewed linearly (as in the 2019 "Straight Cut"), the plot is set in motion by a series of mundane domestic actions and a fateful decision:
- The Pregnancy News: The story actually begins on a peaceful afternoon with Alex (Monica Bellucci) and Marcus in their apartment. They are happy and intimate; it is implied Alex has just discovered she is pregnant, though she hasn't told Marcus yet.
- The Party at "Maison Carrée": The trio (Alex, Marcus, and her ex-boyfriend Pierre) takes a train to a house party. During the train ride and the party, tension builds because Marcus is behaving recklessly—he is heavily using cocaine and alcohol and flirting openly with other women.
- The Fateful Exit: Disgusted by Marcus's behavior, Alex decides to leave the party early and alone. Pierre tries to stop her, but she insists on walking home.
- The Pedestrian Underpass: To avoid crossing a busy street, Alex takes a shortcut through a red-lit pedestrian tunnel. It is here that she encounters Le Ténia, who is assaulting a sex worker. When Alex tries to pass, he turns his attention to her.
Summary of the Inciting Incident
The single action that truly "starts the plot in motion" in terms of narrative causality is Alex's decision to leave the party alone due to Marcus's behavior.
This leads directly to her brutal 9-minute assault in the tunnel, which in turn triggers the "reverse" plot of the film: Marcus's descent into a blind, drug-fueled rage as he forces a reluctant, intellectual Pierre to help him hunt down the perpetrator through the Parisian underworld.
