In the world of modern whodunits, few directors have revitalized the murder mystery genre like Rian Johnson. After the critical and commercial success of Knives Out, Johnson returns with Glass Onion: A Knives Out Mystery, a standalone sequel that swaps the chilly estates of New England for the sun-drenched luxury of a Greek island. This time, master detective Benoit Blanc is thrust into a new circle of suspects, each with secrets, motives, and masks of their own. With a star-studded ensemble, razor-sharp wit, and a plot that peels back layers of deception, Glass Onion is both a love letter to classic mysteries and a sly critique of modern excess and ego.

This review will guide you through the film’s intricate plot, its memorable cast of characters, the underlying themes, its box office and cultural impact, similar films, reasons to watch, a thoughtful conclusion, and answers to the most common questions.

Detailed Plot Summary

The Invitation

Set during the COVID-19 pandemic in May 2020, the film opens with a group of old friends—dubbed “The Disruptors”—each receiving a mysterious, elaborate puzzle box. The sender is Miles Bron, a tech billionaire and co-founder of Alpha, who invites them to his private Greek island for a weekend of fun and a murder mystery game. The group includes:

• Lionel Toussaint, Alpha’s head scientist

• Claire Debella, Connecticut’s governor

• Birdie Jay, a controversial model-turned-fashion designer

• Duke Cody, a men’s rights streamer

• Cassandra “Andi” Brand, Alpha’s estranged co-founder

Each guest solves their puzzle box, except Andi, who smashes hers open. They are joined by Birdie’s assistant Peg and Duke’s girlfriend Whiskey. Unexpectedly, famed detective Benoit Blanc also arrives, claiming he received an invitation.

The Glass Onion

Miles’s mansion, the Glass Onion, is a monument to his ego, filled with glass sculptures and, most notably, the Mona Lisa itself, borrowed from the Louvre. The mansion is powered by Klear, a hydrogen-based fuel that Miles intends to launch globally, despite warnings from Lionel and Claire about its dangers.

Before dinner, Miles reveals the murder mystery game he’s planned, but Blanc solves it instantly, warning Miles that his real-life relationships are far more dangerous than any game.

The Real Mystery Unfolds

Tensions simmer among the group. Andi, once Miles’s business partner, is now estranged after losing a legal battle over Alpha’s ownership. The others, each indebted or beholden to Miles, have secrets and motives to protect their own interests.

During the party, Duke suddenly collapses and dies after drinking from Miles’s glass. Panic erupts, and suspicion falls on Andi, who storms off after an argument. As the group searches for answers, a blackout plunges the mansion into darkness. Shots are fired, and “Andi” appears to be shot and killed.

The Twist: Two Sisters

In a flashback, it’s revealed that “Andi” is actually Helen Brand, Andi’s twin sister. The real Andi was found dead days earlier, but the news hasn’t been made public. Helen, believing her sister was murdered, enlists Blanc’s help to pose as Andi and uncover the truth.

Together, Blanc and Helen investigate the guests, learning that each had visited Andi’s house the day she died. The key piece of evidence is a napkin written by Andi, proving she was the true creator of Alpha’s business plan—a napkin Miles desperately wants to destroy.

The Unmasking

Helen, searching the mansion, finds the napkin in Miles’s office. She reveals her true identity to the group, but Miles burns the napkin, erasing the evidence. The other guests, still unwilling to turn on Miles, refuse to help.

Blanc, having reached the limits of legal recourse, gives Helen a piece of Klear. In a fit of righteous fury, Helen smashes Miles’s glass sculptures. The others join her, and Helen throws the Klear into a bonfire, causing a massive explosion that destroys the mansion and the Mona Lisa.

With the world’s most famous painting destroyed and Klear’s dangers exposed, the guests finally agree to testify against Miles. As police boats approach, Helen and Blanc watch from the beach, knowing justice will be served.

Character Analysis

Benoit Blanc (Daniel Craig)

Blanc is the film’s anchor—charming, eccentric, and always a step ahead. His Southern drawl and keen intellect make him a modern Poirot, but with a warmth and wit that set him apart. In Glass Onion, Blanc is both observer and orchestrator, guiding Helen and peeling back the layers of deception with style.

Miles Bron (Edward Norton)

Miles is the quintessential tech mogul—brilliant, egotistical, and reckless. His charm masks a ruthless ambition and a willingness to destroy anyone who threatens his empire. His obsession with legacy, status, and the illusion of genius is both his strength and his undoing.

Helen/Andi Brand (Janelle Monáe)

Janelle Monáe delivers a standout dual performance. As Andi, she’s the wronged visionary; as Helen, she’s the determined outsider, driven by love and justice. Helen’s transformation from grieving sister to avenging force is the emotional heart of the film.

The Disruptors

• Lionel Toussaint (Leslie Odom Jr.): A brilliant scientist compromised by his loyalty to Miles and fear of losing his career.

• Claire Debella (Kathryn Hahn): A politician caught between ambition and ethics, willing to compromise for power.

• Birdie Jay (Kate Hudson): A fashion icon whose ignorance and self-absorption make her both comic relief and a cautionary tale.

• Duke Cody (Dave Bautista): A men’s rights influencer desperate for validation and fame, ultimately a pawn in Miles’s game.

Supporting Characters

• Peg (Jessica Henwick): Birdie’s long-suffering assistant, the voice of reason amid chaos.

• Whiskey (Madelyn Cline): Duke’s girlfriend, more cunning and ambitious than she first appears.

Themes

The Illusion of Genius

Miles Bron is presented as a visionary, but the film systematically dismantles the myth of the “genius billionaire.” His success is built on theft, manipulation, and the exploitation of others’ talents. The Glass Onion itself—a structure that appears complex but is transparent—serves as a metaphor for Miles’s persona.

Corruption and Complicity

Every member of the Disruptors is complicit in Miles’s rise. Their willingness to overlook his flaws, betray their morals, or actively participate in his schemes highlights how power corrupts not just individuals but entire circles of influence.

Truth, Evidence, and Justice

The destruction of the napkin—a symbol of truth—forces Helen to seek justice outside the law. The film questions whether the legal system can deliver justice when evidence is destroyed and the powerful control the narrative.

The Masks We Wear

Each character hides behind a mask of success, loyalty, or innocence. The murder mystery format allows the film to explore how people construct and defend their identities, even as their true selves are revealed.

Satire of Modern Excess

From the pandemic setting to influencer culture, Glass Onion skewers the absurdities of contemporary life. The characters’ wealth, vanity, and self-delusion are both targets of satire and sources of suspense.

Box Office Collection and Impact

Glass Onion was released in select theaters before premiering on streaming. Despite a limited theatrical run, it grossed approximately $15 million, a strong showing for a film designed primarily for streaming. Its global release on Netflix brought it to millions of viewers, sparking widespread discussion and acclaim. The film’s blend of social commentary, humor, and mystery solidified its place as a standout in the modern whodunit revival.
