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

Angela Bassett, Joan Allen, Connie Britton, Jesse Plemons and Lizzy Caplan co-star in a series about politicians trying to find answers after a deadly cyberattack.

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.
