INSANE: Zero day ending explained breaking down episode 6 of the netflix miniseries - The Real Truth

Lizzy caplan as alexandra mullen speaking at a podium in the tv show zero day.

The new political thriller Zero Day hit Netflix on February 20, 2025, and the six-episode series details the aftermath and investigation into a deadly cyber-attack that claims over 3,000 lives via a blackout event and threatens to destabilize the entire world. Robert De Niro leads the cast as former President Mullen, a well-liked official who comes out of retirement and back into the spotlight to lead the Zero Day Commission with the help of his confidante Roger Carlson (Jesse Plemons) and his former chief-of-staff with whom he had an affair Valerie Whitesell (Connie Britton).

But as Mullen gets deeper into the investigation, he has to contend with an incendiary right-wing talk show host (Dan Stevens) aiming to discredit him by spreading disinformation, a deeply partisan Congressional body, and a top-secret cyber weapon impacting Mullen’s cognitive abilities. Zero Day is wildly realistic in depicting our current political moment and exposing how vulnerable we are to a potential cyber attack, as much of our technological power is currently being consolidated amongst a few individuals.
