When was the last time you gave to a charity, volunteered with an organization or were touched by a friend's passion for a cause? Peter talks about the power of giving—whether it's money from your pocket or time out of your busy schedule—and the big difference that one person can make. He talks with individuals who share their stories of charity and what moved them to open up their hearts and give. "In giving a little of yourself, you just gain so much in so many ways," he says.

Peter speaks with one woman who began feeding hungry children from her home, and now provides annually through her foundation food, school supplies, tutoring and more to nearly 150 children from low-income families. Then, a woman who lost her nephew to gang violence tells Peter how she's helping keep kids off the streets and in school by organizing youth day barbecues and donating school supplies to thousands of students.

Plus, Peter talks to a woman who started a summer camp for children with HIV/AIDS—a place where she says they can experience "an incredible week of fun—without any stigma—unconditional love and support and a place to feel like, 'I'm not the only one living with this situation.'"

Peter is also joined by a man who reveals how his corporation is creating an entire village in Rwanda to help some of the more than 1 million children who were orphaned after genocide ravaged the country. And, Peter speaks to a representative from Oprah's Angel Network, who shares how the charitable organization got its start and what projects are on the horizon.
