Tenet

The Protagonist (John David Washington) enters a world where time is reversed. Laura (Clémence Poésy) explains to him how it works, saying that one of the bullets is like us, traveling through time, and the other one is going backwards. She explains, "You're not shooting the bullet. You're catching it." The Protagonist teams up with English spy Neil (Robert Pattinson), who warns, "Time isn't the problem, getting out of it alive is."
