⚠ Spoilers ahead
Memento ending explained: the film runs backwards so you feel Leonard’s confusion, and its final scene reveals that Leonard is not hunting his wife’s killer at all. He is choosing a lie, because the truth is worse than the hunt.
The Story in Chronological Order
Leonard Shelby, played by Guy Pearce, suffers from anterograde amnesia after an attack in his home. He cannot form new memories, so he lives by Polaroid photographs, handwritten notes and tattoos inked across his body. His stated mission is to find the man who raped and murdered his wife, a man he knows only as John G.

The film tells its story in reverse. Each color scene ends where the previous one began, so the audience discovers the truth at the same pace Leonard forgets it. The black-and-white scenes, told forwards, show Leonard in a motel room, explaining his condition on the phone. The two timelines meet at the end, and the meeting is devastating.
Sammy Jankis: The Man Who Was Leonard
Throughout the film, Leonard tells the story of Sammy Jankis, a man he investigated as an insurance claims adjuster. Sammy also could not form new memories after an accident, and his wife, doubting his condition was real, tested him by asking him to inject her insulin again and again. Sammy gave her the injections, and she died of an overdose.
Leonard insists Sammy’s condition was psychological, not physical, and denies his claim. The film’s final revelation is that Sammy’s story is Leonard’s story. Leonard’s wife survived the attack, but she was diabetic, and she tested Leonard the same way, asking him to give her insulin repeatedly. Leonard, unable to remember the earlier doses, gave her a fatal overdose. He killed his own wife, and his mind buried the memory.
Teddy and the Lie Leonard Chooses
Teddy, played by Joe Pantoliano, is the man Leonard kills in the film’s first scene, which is chronologically the last event. Teddy, whose real name is John Edward Gammell, is a police officer who once helped Leonard track down the real attacker. Leonard killed that attacker long ago, but because he cannot remember, Teddy kept giving him new John G. targets, using Leonard to kill drug dealers and other criminals.
In the final scene, Teddy tells Leonard the truth: his wife survived, Leonard killed her with insulin, and the hunt is a fiction Leonard needs to keep living. Leonard cannot bear it, so he deliberately creates a new lie. He burns his wife’s photograph and the evidence, writes a note telling himself not to believe Teddy’s lies, and sets himself up to kill Teddy next, giving himself a new John G. to hunt.
Along the way, Leonard is manipulated by almost everyone he meets. Natalie, played by Carrie-Anne Moss, uses his condition to get him to kill for her, and the drug dealer Dodd becomes another pawn in a chain of people who know Leonard will forget what they did. That manipulation is part of the tragedy: Leonard’s system of notes and tattoos, built to protect him, is exactly what others exploit.
What the Ending Means
Leonard’s last act is a choice, not a mistake. He knows his memory will erase the truth, so he plants a false purpose that will survive forgetting. The film ends where it began, with Leonard photographing Teddy’s corpse and driving off, ready to hunt a man he has already killed, in a story that will repeat forever.
That is why Memento is told backwards. The audience, like Leonard, starts with certainty and ends with doubt, and the final scene forces you to ask whether a comforting lie is better than an unbearable truth.
