Rian Johnson’s Knives Out is a compelling murder mystery that constantly keeps audiences guessing. With numerous twists, it delivers a surprising yet satisfying ending, revealing the real culprit behind the death of the famous author, Harlan Thrombey (played by Christopher Plummer). At the center of this mystery is Benoit Blanc, a sharp private investigator (Daniel Craig), who is hired to probe Harlan’s apparent suicide after his birthday party. As Blanc investigates, he uncovers that each member of the Thrombey family had a potential motive to kill Harlan, from covering up secrets to inheriting his vast fortune.
Despite the many suspicious family members, only one person is revealed to have orchestrated Harlan’s death: his grandson, Hugh Ransom Drysdale (Chris Evans). The finale of the film unravels through several flashbacks and key twists, making it one of the most talked-about conclusions in modern cinema. With its fast-paced ending, Knives Out can be tricky to follow, especially as the final act is dense with revelations.
Knives Out Ending Explained
The final third of the film shows a heart-stopping twist. Marta, the nurse who attended Harlan, goes to see Fran, the housekeeper, who has discovered Ransom’s true identity as the murderer. Fran, dying from a morphine overdose, holds a crucial piece of evidence: a photocopy of Harlan’s blood test, proving he was not killed by an overdose. Marta, overwhelmed with guilt, confesses to Blanc that she accidentally gave Harlan a fatal dose of morphine. As Fran is rushed to the hospital, Marta nearly admits the truth to the Thrombey family, but Blanc soon realizes that she is innocent.
The story then shifts into a classic murder-mystery style as Benoit Blanc pieces together the events that led to Harlan’s death. He reconstructs how Ransom sneaked back into the house, climbed the trellis, and tampered with the medication. As the pieces fall into place, Blanc lays out the entire scenario before Ransom, who, believing he’s doomed, confesses. However, a twist follows: Fran dies from the overdose, but Marta has recorded Ransom’s confession on her phone. Ransom attempts to flee, but he is captured, and Marta walks away with Harlan’s mansion and fortune.
The Truth Behind Harlan Thrombey’s Death
One of the most unexpected aspects of Knives Out is that Harlan’s death is shown early on, as the film sets up the mystery. Marta is administering Harlan’s nightly medication when an accident causes the vials to fall. In her haste, Marta accidentally switches the vials, giving Harlan a lethal dose of morphine. But the antidote for the overdose is mysteriously missing. Realizing that she would be blamed for the death and fearing for her family’s future, Marta follows Harlan’s instructions to leave and then return to the house, pretending to be him.
Before the morphine can take its deadly toll, Harlan decides to end his life by slitting his own throat, making it appear as though he committed suicide rather than dying from an accident. The film then reveals that Harlan’s death wasn’t an accident at all. It was a plot orchestrated by Ransom, who wanted to set Marta up to take the fall.
How Ransom’s Plan Unfolded
Ransom’s scheme to have Marta unknowingly kill Harlan begins with his resentment after being cut out of Harlan’s will. Harlan’s fortune was left to Marta, and Ransom, motivated by greed, conspired to frame her for his grandfather’s murder. He switched the labels on the medication in Marta’s bag, then stole the antidote, ensuring that no one could save Harlan if he overdosed. However, the plan faltered when Marta mistakenly gave Harlan the correct dose of medication, saving his life.
Despite Ransom’s failure, the situation took a darker turn when he later killed Fran, the housekeeper, to cover his tracks. Fran had discovered his tampering with the medicine and had kept a copy of the blood test, which would have exonerated Marta. Ransom, in a panic, murdered Fran and set up Marta to take the blame.
Ransom’s Plan Goes Awry
Ransom’s original plan involved sneaking back into the house after storming out in anger over the will change. He climbed up the trellis to avoid detection and switched the vials of medication. However, things didn’t go as planned. Fran witnessed Ransom’s actions, and Marta unintentionally gave Harlan the correct medicine, saving his life. Ransom’s plan was already failing, but when he hired Benoit Blanc to investigate, he believed the detective’s skills would ultimately frame Marta.
Ransom then went to great lengths to cover up his involvement, even burning the lab where Fran’s blood tests were stored. But Fran had kept a copy of the test, and before she died, she sent Ransom a warning, “I KNOW WHAT YOU DID.” Ransom tried to set Marta up by sending her a message, tricking her into thinking the blood test would prove her guilt.
Ransom as the Villain: A Perfect Choice
Ransom is the ideal villain in Knives Out, perfectly crafted to surprise the audience. From the start, he is portrayed as an arrogant, entitled figure who stands out among the Thrombey family members. While the family members are all suspicious, Ransom’s behavior makes him appear both obvious and inconspicuous as the culprit. The way the film misdirects the audience into believing Marta is the killer only makes Ransom’s ultimate revelation more impactful.
The film subtly manipulates the audience’s expectations, leading them to believe in Marta’s guilt before turning the tables. The fact that Marta, the kind-hearted nurse, is deceived by Ransom’s villainy mirrors the audience’s own false assumptions, making the reveal of Ransom as the true killer more satisfying. His cold, calculating nature contrasts sharply with Marta’s genuine goodness, making her triumph over him all the more rewarding.
The Deeper Meaning of Knives Out’s Conclusion
Despite the tragedy of Harlan’s death, the film’s ending is ultimately optimistic. Marta, though flawed, proves to be a truly good person. Her attempt to cover up Harlan’s death was driven by a desire to protect her family, but her guilt weighs on her. She could have let Fran die to avoid the consequences, but her good nature prevailed, and her actions saved the day.
The movie critiques the entitlement of the Thrombey family, who believe they deserve Harlan’s wealth because of their family connections and inherited success. In contrast, Marta receives Harlan’s fortune because she is kind to him without any hidden agenda. Knives Out challenges the notion of inherited wealth and the entitlement that comes with it, making a statement about privilege and the importance of genuine goodness.
