If we could pick one word to describe Christopher Nolan’s sci-fi thriller, Tenet, it’d be confusing. You’re probably in the same boat, which isn’t necessarily surprising for Nolan – he’s responsible for mind-bending masterpieces like Interstellar and Inception – but still, if you left the theatre wondering what the heck all that was about, you wouldn’t be the only one. Did Nolan bite off more than he could chew with Tenet, or is this the work of a genius that only fellow geniuses can even come close to understanding? Let’s dive in.

Understanding the Basics: Time Inversion and The Protagonist’s Journey
For the fuzzy-minded (like us), Tenet is a film about the flow of time and the potentiality of its inversion. We’re not talking about time travel in the strictest sense of the word, but an object or a person’s ability to move backward through time. John David Washington plays the Protagonist (yes, that’s all we know him as) who falls into this world without much hope of getting out of it.
Washington is recruited by an organization called Tenet, which aims to stop Andrei Sator, a ruthless arms dealer (Kenneth Branagh). Sator has one hand in the future, where he is attempting to devise a formula that could completely wipe out the present.

As the Protagonist attempts his mission, he encounters several fascinating, albeit complex characters, including Neil (Robert Pattinson), Kat, Sator’s wife (Elizabeth Debicki), and Laura (Clemence Poesy), the scientist who explains everything to him by showing him the inversion of time with a bullet. These characters link the Protagonist to a story seen from many different perspectives and angles, including, of course, through time inversion.
The Entropy of Relationships: Character Dynamics and Temporal Effects
As you might have guessed, the timeline of relationships in Tenet is as complicated as the plot, particularly the relationship between Kat, Neil, and the Protagonist. The Protagonist’s connection with Neil is essential to the film’s resolution because it is ultimately revealed that Neil’s bond with the Protagonist transcends what is happening in the present. This illustrates how a connection built on faith and trust can overcome boundaries like time, highlighted by Neil’s final act of self-sacrifice.
To keep things spicy, Nolan also examines Kat’s relationship with the antagonist, Sator. He reveals his controlling nature, while Kat is determined to protect her son at all costs. The scenes shot in Vietnam, particularly in the climax, highlight Kat’s essential role in Sator’s ultimate downfall. She is forced to confront her past and change her future.
The Algorithm and Its Consequences
The algorithm or formula Sator is obsessed with comprises nine pieces hidden throughout time by a future scientist. She understands the potential destruction of her creation, hence her desire to keep it from getting into the wrong hands. This creation can reverse the entropy of the entire world, inverting the flow of time and ultimately resulting in the past destroying the future. Sator’s driving force for finding this creation is his cancer diagnosis—if he can’t survive, neither can anyone else.
The Temporal Pincer Movement
Another fascinating concept highlighted in Tenet is the temporal pincer movement, a time-travel theory. This theory is executed through two teams in a car chase scene, one moving forward in time while the other is inverted. The goal is to implement a coordinated attack or defense. One side is the red team, while the other is the blue team. This visual demonstration reflects the plot, which constantly moves back and forth in time to reveal new perspectives and angles.
Figuring Out Tenet’s Ending
If you’ve seen the film, you’ll know how confusing and layered the ending is (warning: spoilers). The Protagonist discovers that he is the future version of the protagonist who founded Tenet and recruited everybody, bringing the story full circle. Neil also reveals his connection with the protagonist, a subplot illustrated by a red string on his backpack. The Protagonist’s final interaction with Priya (Dimple Kapadia) ensures that her silence protects the future and shows him accepting his own role in the story and the burdens that come with it.
The final scene introduces another theory, called the grandfather paradox, and the movie’s stance on the permanency of time. Our understanding of the plot and the Protagonist’s actions are deliberately left ambiguous, driving home just how mysterious everything is.
Tenet is undoubtedly one of Nolan’s most ambitious projects to date. From the cleverly executed Memento to the unforgettable Dunkirk, it’s clear that Nolan’s overarching goal is to push storytelling boundaries, whatever the plot might be.
