Ever since I was a child, my entire life has centred around death.

I was born in a country where the threat of violence, terrorism and assassination is a daily struggle.

My younger sister Tali, the sole truly innocent person in my family, died as a teenager in a suicide bombing. A bombing conducted by a group dedicated to the destruction of my country of birth.

My father is the director of a spy agency which abducts, tortures and assassinates people on his orders- without question.

My half-brother Ari, a man who became a monster because of what surrounded him, was used by my father and then betrayed him. He became part of a terrorist cell plotting an attack in the capital of the world's most powerful country. He killed a former Secret Service agent who worked for a naval investigative agency. And he died in the basement of the leader of that team. He died- by my hand.

As for myself, my job was predetermined before I was born. I was trained, programmed from the day of my birth to be the most effective ruthless assassin in the Mossad. I was never a daughter to my father. I was never even a human being. I was a tool- a weapon to be used at my father's command.

I lived that life for a long time without protest. I endured the worst pain and suffering a human being could endure- until I decided to get out of it. I became an American citizen and joined the same team I had been attached to for years on a permanent basis. I believed that the worst days of my life were forever behind me.

Until now.

Now we face an enemy that poses a greater threat than any other we have faced before. An enemy that has caused the disappearance of countless individuals across the world- regardless of nationality, religion, ethnicity or orientation.

They do not operate under any flag. They do not proclaim loyalty to any country. They do not subscribe to any ideology.

We do not truly know why they do what they do. But right now, that is irrelevant.

Because we are going to stop them.

To do that, it is necessary that we work among people we do not trust in the slightest. Individuals we may very well have been fighting against under different circumstances.

That is the price of success in this mission.

A mission we are unlikely to return from.

I will not fight this battle as an assassin under Israel's Star of David.

I will not fight this battle as an federal agent under the stars and stripes of America.

I will fight this battle as a human being.

For we face an enemy that is inhuman. An enemy that has struck at the very core of NCIS.

Now it is our turn to return the favour.

My name is Ziva David.

And I will fight until my last breath.

We are going to find the ones responsible for these atrocities.

And we are going to kill them.
