Formerly known as naysayer Andrea on The Walking Dead, actress Laurie Holden also happens to participate in undercover sting operations by a human rights organization called Operation Underground Railroad, run by a former CIA Agent, Homeland Security Investigator, and Navy SEAL. In this week's Nightline, you can see her in action, taking down monsters way worse than comic book zombies.
