Here's a pretty unbelievable story: Laurie Holden is an actress who plays Andrea on "The Walking Dead," but she isn't just an actress.

Holden also works as a human rights activist with a group called Operation Underground Railroad.

It's an organization run by an ex-CIA agent named Tim Ballard that works to take down unsavory human traffickers and the like.

So, Holden and the group went down to Colombia to try to take down a group of men who were trafficking in underage prostitutes. Ballard, Holden and co. ingratiated themselves into this group and set up an elaborate party in an effort to catch these men in the act.

The party was held at a massive mansion and the sex traffickers believed it was an event set up to facilitate the sale of these underage girls to interested parties.

A film crew as well as Colombian law enforcement were hiding out during the party.

Holden watched over the young girls as Ballard coerced the traffickers into making a faux transaction with him. Once that happened and was caught on tape, the police jumped out and arrested the guilty parties.

All in all, 55 young girls were rescued. And it's in no small part to the work of Laurie Holden. Doesn't that beat any episode of TV you've seen lately?
