Joker: Folie à Deux

During a television show performance, the Joker unexpectedly finds himself replaced by his own shadow while singing. Three policemen arrive shortly after and brutally assault him, leaving him bewildered and injured on stage.

Arthur Fleck is now in custody at Arkham State Hospital, awaiting trial for his prior violent actions committed two years ago. His lawyer, Maryanne Stewart, is preparing a defense centered around his dissociative identity disorder, which connects him to his violent alter ego, the Joker.

Arthur meets Harleen 'Lee' Quinzel during a music therapy session in Arkham’s B ward. Lee reveals her tragic childhood and expresses admiration for the Joker, hinting at a dark fascination with his notorious deeds.

While watching a screening of *The Band Wagon*, chaos ensues as Lee sets a fire, leading to their capture during an attempted escape. This act results in Arthur being confined to solitary, raising the stakes in their tumultuous relationship.

Although Lee plans to separate herself from Arthur's influence, she promises to support him during his trial. Their connection deepens with a brief intimate encounter, showcasing the complexity of their relationship.

In an interview with television host Paddy Meyers, Arthur serenades Lee through the screen, further intensifying her infatuation with him. This moment highlights their bond and the depth of Lee’s admiration for Arthur's alter ego.

On the day of the trial, Assistant District Attorney Harvey Dent presents witnesses who contradict Arthur's claims of insanity. This crucial moment sets the stage for a dramatic courtroom battle, stirring tensions and expectations.

In a shocking revelation, Maryanne unveils Lee’s true identity as a psychiatry student whose father is alive. This exposes the lies Lee told Arthur about her past and complicates their relationship as the trial progresses.

Choosing to represent himself, Arthur hears testimonies from Gary Puddles and Sophie Dumond that deeply shake him. Instead of offering a defense, his speech ridicules the Arkham guards and hints at the abuse he has faced.

After the trial, Arthur is sent back to Arkham, where he suffers a brutal assault from the head guard and others. This barbaric act culminates in the tragic death of his friend Ricky, showcasing the harsh reality of life in prison.

In a poignant closing statement, Arthur rejects his Joker identity and takes accountability for his actions. This renunciation enrages Lee, leading to her departure and foreshadowing the chaos to follow.

The courtroom reaches its climax when Arthur is found guilty of first-degree murder. Just as the verdict is read, a car bomb detonates outside, causing mass casualties and leaving Assistant District Attorney Harvey Dent severely scarred.

In the chaos following the bombing, Arthur’s followers help him escape from the courthouse. This moment marks a significant turning point, reigniting his infamous legacy as the Joker.

Arthur finds Lee outside his former residence, but she turns him away, upset over his rejection of the Joker persona. This heartbreaking encounter highlights the emotional turmoil in Arthur's life.

As Arthur is recaptured by the police, he faces betrayal from a young inmate who approaches him with a joke before stabbing him. In his final moments, Arthur succumbs to his injuries, leaving a haunting image with the assailant laughing maniacally.
