Mia Farrow: A Trip to Darfur

In June, actress Mia Farrow returned from a weeklong trip to Darfur, the conflict-ravaged region in western Sudan, with images of "unthinkable suffering" – and a passion for the people who have survived. “The people I met, the stories I heard – all of it is seared into me,” Farrow, a UNICEF Goodwill Ambassador, tells PEOPLE. “I am not the same person anymore.” Here are her photos and recollections of her journey.

SWEETNESS AMONG SUFFERING

"This girl's face epitomized all the reasons why we cannot be disconnected from this tragedy," says Farrow, who visited the Zam Zam Refugee Camp – one of 200 in the region. "In her face, you see all the sweetness and beauty and hope and trust. Just look at her – it sort of says it all. This little girl had never seen a picture of herself. So I took her picture and then turned the digital camera around so she could see it."
