Glass Onion: A Knives Out Mystery

In May 2020, during the COVID-19 pandemic, Helen Brand seeks out detective Benoit Blanc to investigate her twin sister's suspicious death. Her sister, Cassandra 'Andi' Brand, had apparently taken her own life just days prior, raising questions about the circumstances surrounding the tragedy.

Hours before her death, Andi sends an email to her business partner, Miles Bron, threatening to expose incriminating evidence against him. This email raises alarms as Helen suspects that Andi's death might have been a murder rather than a suicide.

Following the suspicious circumstances of Andi's death, Helen receives a mysterious invitation to a murder mystery weekend hosted by Miles Bron on his private island in Greece. With Blanc's guidance, Helen decides to pose as her deceased sister to uncover the truth about what happened.

Andi was once the CEO of Alpha, a tech company she co-founded with Miles. After a significant disagreement over a potentially dangerous product launch, she was ousted by Miles, leading to a devastating lawsuit that she unfortunately lost.

As Helen investigates further, she learns about a crucial piece of evidence hidden in a red envelope that Andi had mentioned. This evidence is suspected to be detrimental to Miles, strengthening Helen's resolve to uncover the truth behind her sister's death.

Blanc and Helen begin to unravel a web of deceit surrounding Andi's former friends, including Lionel, Claire, Birdie, and Duke. Each individual's history with Andi and Miles reveals a complex entanglement of motives, raising suspicions about their involvement in her demise.

As the weekend progresses, tensions among the guests escalate. Helen digs deeper into the relationships within the group, uncovering potential threats and hidden motives that connect them to Andi’s tragic fate.

During a lavish party, a shocking event occurs leading to the sudden death of Duke Cody, triggering panic among the guests. This unexpected twist throws the investigation into turmoil and raises further questions about the true nature of Andi's death.

Determined to find the truth, Helen puts herself in harm's way when an unknown assailant shoots at her. Miraculously, Andi's journal saves her, acting as a crucial piece of evidence in the case that reveals more about the events leading to Andi's death.

The investigation reaches a peak in Miles's art room, where Helen confronts him about his deceitful actions. As tensions flare, Miles attempts to eliminate any threats to his empire, further exposing his desperation to silence the truth.

In a dramatic finale, the Glass Onion mansion begins to crumble as truths are revealed. Amidst the chaos, the guests unite against Miles, whose downfall becomes inevitable as the stakes rise to monumental levels.

In an act of desperation, Miles's attempts to destroy vital evidence lead to the destruction of the famous Mona Lisa. This act symbolizes the lengths he will go to preserve his power and the moral cost of his actions.

As the authorities arrive, the guests reflect on the events that transpired. Helen and Blanc find solace in knowing that justice will finally be served, bringing closure to the tragic series of events that unfolded over the weekend.
