On this international day of the girl, let's turn to malala. She showed everyone. And she showed us her bravery. She was here in new york last night with her father. Bravely in incredible odds. Inspiration to many. And diane sawyer is here with a preview of her exclusive hour with the young pakistani, 16-year-old, malala. Taking her fight and inspiring and moving interview. You spent so much time with her. We heard from her this past week. And it's great to see that. Hello. Good to have you back here. We have to be reminded, this has been an incredible year this young woman has had. A year since she was shot. A miraculous recovery in the hospital, with amazing things we'll be explaining to you tonight. Also, her step-by-step return, fearlessly, unbreakibly, to the front lines of girls' education is something to behold. I always say, gather around every child who ever complained about school, and also, who has fear in their own life, and see what she does. And I want to remind everybody, how it happened a yeargo because she has become a force that no one thought the taliban would take on a child. And yet, there she was, on the school bus. The kids were singing. And here is what happened. October 2012. A group of schoolgirls in the swatt valley, singing. But two men approach. One of them with a colt .45. He climbs on the bus and asks this question. Who is malala? She doesn't remember what happened next. But her friend describes the moment. She said, say nothing and you will just -- you were just holding my hand. And you squeezed my hand like you were forcing it. And you said nothing. And she said, like, you just looked at the man like this. Then, she says that when he fired three bullets. And one hit you on the left side of my head. Reporter: She was shot in the head at point-blank range. A year later, a miraculous recovery. And a new message for the world. I think life is always dangerous. Some people get afraid of it. Some people don't go forward. But some people, if they want, they have to go. And the threat is still there. It's telling me to move forward. She is able to express herself in such a way. But she's really up against quite a bit, even with fellow muslim women. That's right. We're going to go out and remind you how entrenched they are. How deeply they believe and ferociously the taliban believes that she is trying to promote democracy and freedom, which cannot co-exist with their radical islam. We talk to women out there. That's the biggest surprise of all. These women, under -- their faces hidden, except for their eyes. They're going to try to explain to me why they oppose her. How can they oppose her? And we'll try to ask those questions proepingbingly tonight. I heard the exchange of you and that group. And we've been saying, it's the international day of the girl. How fitting that malala, on this day, and she is so forward in speaking about what is so important. That's right. And even though she is a child, she shows me her magic tricks. And wants to know why I'm not double-jointed and trying to get me to practice. In so many ways, she's a child-turned-gladiator. And says, who is going to speak up if I didn't? Here she is now. The movement has begun. And everyone at home, I think it leaves you soaring to know that you can join and say, I am malala, too. And 31 million girls have been silenced have a right to be heard. It's so powerful when you hear all different -- everybody saying that. Diane, always good to have you here. We will be watching tonight. "Unbreakable," on "20/20," 10:00, 9:00 central. And malala's autobiography is out the this week. Entitled, "i am malala." You want to introduce sam?
