Oprah's Big Give has landed in Oprah's hometown of Chicago, and she's gathered the final three contestants at the world-famous Grant Park to tell them about their next mission: The Big Family Reunion. For the first time since the competition started, Brandi, Stephen and Cameron will be reunited with their loved ones. But going home won't be a vacation. Each giver will be given four days and $10,000 to find people in need and give big in a dramatic, creative and exciting way.

"Don't let your hometown down," Oprah says. "Your challenge starts now!"
