Zero Day Ending Explained (In Detail)




 Finally, Zero Day has arrived. Here is an explanation of what transpires at the miniseries' conclusion. One of the most eagerly awaited streaming debuts of 2025 is Netflix's Zero Day, which is particularly noteworthy due to its all-star cast and outstanding creators. There is a lot to analyze now that all six of Zero Day's episodes have been made available, as the intricate political thriller takes many unexpected turns. Here is what transpires at the conclusion of Zero Day, what questions remain, and how Zero Day might relate to everyday life.

George Mullen, played by Robert De Niro, is a former president who must come out of retirement after a devastating cyberattack destabilizes the entire world in Zero Day. Because of the former president's immense popularity, Mullen is appointed head of the Zero Day Commission; however, this popularity wanes as his methods become more authoritarian over the course of the series. Before disbanding the Zero Day Commission, Mullen exposes the Zero Day conspirators, who he learns are actually government officials who carried out the attacks to further their own agendas.

The Zero Day Attack's Mechanism

With snippets of code mentioning Euromaidan, it was initially believed that the Zero Day attacks were Russian in origin. The Zero Day Commission, however, later came to the conclusion that the Russian allusions were merely red herrings and that the Zero Day attacks were the work of a U.S.-based left-wing extremist organization. Both of these trails turned out to be false leads, and the Zero Day Attacks were actually the brainchild of some of the wealthiest and most influential people in the United States.

In Zero Day, Monica Kidder is a tech tycoon, and her apps were the cause of the Zero Day Attack. The exploitable code in Kidder's apps, which are said to be on 80% of phones worldwide, enables them to break into nearly every piece of technology and force it to shut down for a minute. It was never clear how Kidder's app managed to do this undetected because Kidder either committed suicide or was killed while incarcerated. However, this weakness proved to be extremely dangerous, resulting in numerous fatalities and significant instability on a worldwide scale.

Every Individual Taking Part in the Zero Day Attack: Every Conspirator

Near the end of the series, George Mullen acknowledges that the Zero Day Commission is far from finished identifying all of the conspirators who were involved in the Zero Day Attack. There are a few primary ones, though. George Mullen initially finds out about the attacks from his daughter, Alexandra Mullen, who works inside the government. According to Alexandra, she and a number of other members of Congress were aware of the attacks prior to their occurrence, and Richard Dreyer informed them that the unrest would usher in a new era of American power and solidarity.

In the meantime, a number of influential people from outside the government were also engaged. As previously mentioned, the attacks were made possible by Monica Kidder's apps, which she permitted to be used to breach various technological systems. A significant role was also played by wealthy investor Robert Lyndon, who spoke with the different conspirators and even shorted the market prior to the attacks in order to take advantage of the unrest. By the end of the series, George Mullen has named a number of other minor co-conspirators, and the Zero Day plot extends well beyond the show's main cast.

The Reasons George Mullen Didn't Disclose the Conspiracy

George Mullen shares the Zero Day Commission's findings during a press conference at the conclusion of the Zero Day finale. Although Mullen was initially authorized to discuss Kidder and Lyndon's involvement in the plot, he deviates from the plan by disclosing the government officials who were complicit. Mullen took this action to expose government corruption because he thought elected officials ought to look out for the common good rather than ducking harsh realities. Mullen was moved by his daughter's decision to come forward and felt that everyone else should be held accountable.

What Was Robert Lyndon Up To?

Since it's unclear exactly what Robert Lyndon got up to at the end of Zero Day, his fate is a little unclear. In one scene, Robert Lyndon is on his yacht, still using online communication to conceal the Zero Day Attacks. While there, Lyndon reveals that he is getting ready to leave the nation, taking his fortune and setting sail. This is probably what transpired after Zero Day ended, with Lyndon using his wealth to start over and escape his repercussions.

What Takes Place Following the End of Zero Day

The world still needs to recover greatly from the Zero Day Attack, so even though Zero Day does conclude with episode 6, the story is far from finished. The Zero Day Commission is officially coming to an end, so George Mullen can go back to retirement, as he states in his presentation. He adds, though, that the government is still investigating the conspirators, with the unidentified conspirators still being sought out and the named conspirators being charged.

Furthermore, Mullen adds that a strong cyber-security package is required to guarantee that the Zero Day Attacks never occur again. One of the main plotlines that will continue after Zero Day is the government's efforts to thwart any more attempts at cyberwarfare. After all, these vulnerabilities need to be addressed quickly because there is still a chance that additional Zero Day attacks could occur after the first two.

Can There Be a Zero Day in Real Life?

In fact, the Zero Day Attack depicted in Zero Day might occur in real life. Since transportation and medical systems would not be able to operate, it is likely that a one-minute shutdown of all global communication systems would result in a variety of fatalities. Although it is unlikely that an attack of this nature would be carried out using the hacking technique outlined in Zero Day, our dependence on technology does leave us open to these cyberthreats. Therefore, Zero Day serves as a warning of a genuine threat, even though some of its elements may be exaggerated.
