The fifth episode of the Brave Nation series featuring Naomi Klein and Tom Hayden is being released this Sunday. Take an exclusive sneak peek at author, activist and Nation columnist Klein discussing the factors that first pulled her into activism.

And watch Hayden talking about how and why people join social movements.

A kind of “living history” project composed of produced videotaped conversations, This Brave Nation, a collaboration between The Nation and Brave New Films, brings together the most intelligent, passionate and creative voices of one generation with the activists, journalists and artists of the next to dialogue on loves, lives, politics and history.

Check out past episodes.

Help organize a house party to screen the series, including a live event on July 13 with Nation editor Katrina vanden Heuvel and Brave New Films founder Robert Greenwald.
