Let's break down the explosive series finale of Netflix's "Zero Day," a cautionary tale about autocracy, misinformation and cyberterrorism.

Zero Day had everyone talking when it was first announced, with many noting that Robert De Niro doesn't do many TV shows. I was intrigued to see him playing a troubled former President, as Netflix has a record for being pretty good with political thrillers.

De Niro stars as former U.S. President George Mullen. Part of his role includes leading the Zero Day Commission, an investigative group specializing in cyberattacks.

For Lizzy Caplan, joining Netflix's "Zero Day" was an easy decision to make, citing Robert De Niro's involvement, as well as the "solid" credentials of co-creators Eric Newman, Noah Oppenheim and Michael Schmidt.

Can you handle a cyberattack in this computer age when everybody is completely dependent on the internet, phones, and computers? And who do you think would be able to save the world from such a crisis?
