Volker Türk has the greatest respect for those able to hold onto hope when all appears to be lost. As United Nations High Commissioner for Human Rights, he has devoted his life and career to helping the world's most vulnerable people.

"What has always struck me was encounters with people who are extremely resilient … who actually see hope, including in the most atrocious circumstances, and who just keep doing the right thing."

The Office he leads works around the world to uphold human rights, speaking out against all abuses and empowering people to claim their rights. In this episode, Volker Türk reflects on holding rulebreakers to account, the strength displayed by refugees, and why the best ideas often arrive in the dead of night.

"Human rights … is the strongest tool that we have in our hands to be a voice of those who don't have power and to speak truth to those who have the power and to make sure that they understand that yes, that there are limits to power."
