In an upcoming episode of National Geographic Channel’s new series “Inside: Secret America” journalists Mariana van Zeller and Darren Foster investigate the world of animal activism from both sides.

The episode, titled “Inside: Secret America: Animal Undercover” airs Wednesday, July 31, at 10:00 p.m Eastern Daylight Time. It includes interviews with animal activists who lead hidden camera videotaping on food animal farms, as well as an interview with Animal Agriculture Alliance CEO Kay Johnson Smith.

“While activists push for stricter enforcement of animal cruelty laws and increased criminal prosecutions against offenders, industry executives and lawmakers are mounting their own counterattack, pushing for tougher laws to criminalize covert activism. Van Zeller and Foster meet with people on both sides to examine the story,” according to promotional materials for the show.
