Overview
When a devastating cyberattack shuts down power, transport and communications across the United States and leaves thousands dead, former President George Mullen is pulled out of retirement to lead the investigation. Tasked with finding who was behind the attack, Mullen soon discovers that the truth is far messier than a single enemy. Every lead opens another door: political rivals with something to hide, intelligence officials protecting their own turf, a family fractured by ambition, and a public already primed to distrust everything it is told. As Mullen chases the source of the attack, he must also confront his own memory, his judgment and the secrets of his past. Zero Day turns a national crisis into a tense, personal thriller about power, paranoia and the danger of believing a simple story in a complicated world.

Why Watch Zero Day?
Zero Day is a tightly wound political thriller that never lets its central mystery go slack. Robert De Niro anchors it with a weary, stubborn authority, and the supporting cast keeps every alliance feeling uncertain. It is the rare conspiracy drama that asks as much about truth and trust as it does about who pressed the button.
