One in three women are raped or beaten in their lifetime. That equates to one billion of the women alive today.

After suffering abuse as a child, Eve Ensler became an activist. Two decades of activism culminated last year with One Billion Rising. It was "a global call for women and men across the planet to rise, and dance, and end violence against women and girls." And rise they did.

Eve told Becky, "what was really exciting I think is to see not only the breadth of the huge risings, massive risings in places like Philippines, and India, and Bangladesh, and at the Brandenburg Gate in Berlin for example, but to see these individual risings that happen, like with a girl in Tehran in her bedroom who filmed herself, in the streets of Somalia where women had never, in the history of Somalia, broken through and danced in the streets, in Lebanon. We saw people come out of the woodwork... It was a feminist tsunami."

Now a short film about the V-Day Rising has been selected to premier at the Sundance Film Festival, creating more awareness and more empowerment among women across the globe.

"I think there's an unearthing going on. The stories are finally coming out. What's been happening forever is finally getting told."
