Plot Details

Zero Day is a political thriller that unfolds in the wake of a catastrophic cyberattack that devastates the United States. The attack cripples infrastructure, wipes out critical data, and leads to widespread chaos, ultimately resulting in the loss of thousands of lives. As panic grips the nation, tensions mount both domestically and internationally, pushing an already divided society to the brink of collapse.

At the center of the crisis is former U.S. President George Mullen (Robert De Niro), a seasoned political figure who once led the country through turbulent times. In the wake of the disaster, Mullen is called back into service to chair the Zero Day Commission, a high-level task force dedicated to uncovering the perpetrators behind the attack. However, as the investigation unfolds, Mullen and his team soon realize that the conspiracy runs far deeper than anticipated—pointing to hidden forces within the government, private corporations, and possibly even foreign adversaries.

The series delves into themes of misinformation, government secrecy, and cyber warfare, mirroring contemporary anxieties about technological vulnerabilities and geopolitical power struggles. Inspired by classic conspiracy thrillers such as The Parallax View, Marathon Man, and Three Days of the Condor, Zero Day delivers a gripping, paranoia-fueled narrative where trust is scarce, and the truth remains elusive.
