The court system faces overwhelming challenges due to a surge in criminal activities, leading to the adoption of a groundbreaking bench trial system designed to expedite case resolutions. In this innovative setup, both the prosecution and defense engage in open court, racing against the clock with just three days to present their arguments before the judge delivers a verdict.
Phoenix Wright, a rookie defense attorney, has recently celebrated his first victory by successfully defending his friend Larry Butz against a wrongful murder accusation, under the guidance of his esteemed mentor, Mia Fey(/person/reid-dan). As a token of gratitude, Butz gifts Mia a statue of The Thinker. However, Wright's journey takes a dark turn when Mia is shockingly bludgeoned to death in her office with that very statue, and her younger sister, Maya Fey](/person/mirei-kiritani), who possesses spirit medium abilities, finds herself implicated due to a dying note left by Mia. In a fierce showdown against his childhood friend Miles Edgeworth, Takumi Saitoh, Wright ingeniously reveals that Mia's murder was orchestrated by the unscrupulous photojournalist Redd White, resulting in Maya’s exoneration.
In a heartfelt moment, Wright confides in Maya, who subsequently joins him as his assistant, revealing that his decision to become an attorney stemmed from a traumatic childhood incident where he was falsely accused of theft, with Butz and Miles standing by him in defense.
As the plot thickens, Wright receives alarming news of Miles's arrest for the murder of attorney Robert Hammond. Wright, unwavering in his resolve, persuades Miles to allow him to take on his defense. They are pitted against Miles’s formidable mentor, Manfred von Karma](/person/ryo-ishibashi), a prosecutor notorious for his unblemished record and ruthless methods. In the face of daunting challenges, Wright cleverly uncovers the truth that Yanni Yogi, implicated in a notorious case from fifteen years ago, is the real murderer of Hammond. This incident, known as the "DL-6" case, centers around the tragic death of Miles’s father, Gregory Edgeworth, who was fatally shot amid evidence mishandling in the courtroom. Once a bailiff, Yogi's life spiraled into despair following his forced insanity plea by Hammond, ultimately leading to personal tragedy.
After confessing to the courtroom drama, Yogi blames his misfortunes on a package containing a gun that incited his desire for revenge against both Hammond and Miles. Upon hearing Yogi’s confession, Miles shockingly claims responsibility for his father's death, reigniting a fresh investigation into the DL-6 case.
Wright’s dedication leads him to exonerate Miles and reveals damning evidence against von Karma, who is ultimately exposed for perjury and the murder of Gregory. But the original gun, believed to be the weapon of the crime, remains elusive. In a critical turn of events, as Wright contemplates his strategy, he inadvertently shatters the statue of The Thinker, discovering Mia's hidden notes related to the DL-6 case and a bullet that had fatally wounded Gregory, unveiling the reasons behind her own untimely death.
Using this pivotal evidence, Wright successfully incriminates von Karma, who collapses under the weight of his guilt in court, leading to his arrest for murder and conspiracy. Consequently, the judge clears Miles of all accusations, allowing for a much-deserved reconciliation between him and Wright. Determined to restore justice, Wright pledges to aid Yogi in clearing his name, while Butz eventually reveals that it was he who stole the money from Wright during their youth, clarifying past misunderstandings.
Maya, in pursuit of further honing her skills as a medium, takes a temporary leave. Meanwhile, Wright and Miles embrace their respective careers as prosecutor and defense attorney, transforming from adversaries into amicable rivals. Their newfound collaboration and mutual respect hint at promising possibilities for the future, reiterating the notion that in the world of law, justice may sometimes prevail against overwhelming odds.
