Zero Day is an American political thriller, in which Robert De Niro stars as former US president George Mullen, who is called out of retirement and given free rein in leading investigations into an unprecedented cyberterrorist attack, which left thousands of Americans dead.

There are six gripping episodes, each one taking the Zero Day commission a step closer to the perpetrators and at the same time deepening the mystery and delving further into conspiracy theories.

As the threat of a second attack looms and voices raising questions about the legality of the commission and its possibly unconstitutional powers grow louder, Mullen is haunted by another challenge – is he losing his mind or has he been targeted by a top-secret discontinued weapon that has fallen into the wrong hands?

To make matters more complicated, his shady right hand is disconcertingly close to Mullen’s estranged daughter, who is put in charge of a committee overseeing the commission.

As Mullen starts to reel in suspects, doubts are cast over his integrity and his ability to carry investigations forward, while pressure mounts from the president who is hoping to run for re-election.

The series examines the quest for answers, the fight for what is right and the overwhelming price of the truth.

Faced with political and personal dilemmas, enticing ways out and more to lose than to gain, the question right till the end is, what will Mullen ultimately do?

The struggle between good and evil, patriotism and egotism in equal doses, conspiracy, corruption and compromise, and one looking out for the other, all in the right amounts, with a brilliant cast led by De Niro, make for an interesting weekender that will keep you engaged without being too dark or politically incomprehensible.

The television miniseries was created by Eric Newman, Noah Oppenheim and Michael Schmidt for Netflix and directed by Lesli Linka Glatter.

Starring Robert De Niro, Lizzy Caplan as the daughter, Jesse Plemons as the personal aide, Joan Allen as the former First Lady and Connie Britton as the commission’s chief of staff.
