"Call + Response" is a first of its kind feature documentary film that reveals the world's 27 million dirtiest secrets: there are more slaves today than ever before in human history. "Call + Response" goes deep undercover where slavery is thriving from the child brothels of Cambodia to the slave brick kilns of rural India to reveal that in 2007, Slave Traders made more money than Google, Nike and Starbucks combined. Luminaries on the issue such as Cornel West, Madeleine Albright, Daryl Hannah, Julia Ormond, Ashley Judd, Nicholas Kristof, and many other prominent political and cultural figures offer first hand account of this 21st century trade. Performances from Grammy-winning and critically acclaimed artists including Moby, Natasha Bedingfield, Cold War Kids, Matisyahu, Imogen Heap, Talib Kweli, Five For Fighting, Switchfoot, members of Nickel Creek and Tom Petty's Heartbreakers, Rocco Deluca move this chilling information into inspiration for stopping it.
