Here's your heroic news of the day: Laurie Holden, the actress who played Andrea on The Walking Dead, is a member of an undercover organization that helps rescue child victims of sex trafficking in Colombia.

Operation Underground Railroad is headed by ex-CIA agent Tim Ballard, and their dangerous missions are all being documented for a film titled The Abolitionists.

ABC reports:

For months, the group put together a massive sting operation in cooperation with Colombian authorities. They each had an elaborate cover story. Ballard's story was that he was the best man in a wedding back in the U.S. and was looking to hire several underage prostitutes for a big bachelor party in Cartagena. The cover was meant to lure the sex traffickers into a setup so that Ballard and his team could rescue the girls, many of whom were under 18.

Ballard's team features a ragtag group of volunteers, some off-the-books operatives and one former Navy SEAL, but many just regular civilians. There are two CrossFit instructors from Utah, a door-to-door salesman, and even Hollywood actress Laurie Holden, who starred in "The Walking Dead."

The group's objective was to catch alleged sex trafficker Marcus Bronschidle on hidden camera:

Prostitution is legal in Colombia and widespread, but the country's tolerance for prostitution does not extend to children or the people who traffic in children. Those who do face up to 16 years in prison.

In order for Colombian officials to prosecute the sex traffickers, they have to catch them exchanging money for the girls on tape.

Go, Andrea. Holden's job was to "keep [the traffickers] occupied by the pool area while Ballard and the undercover officers worked to catch the traffickers on tape exchanging money." Watch ABC's footage below.
