Former U.S. government agent Tim Ballard, founder of Operation Underground Railroad, pulls back the curtain on the real-life stories that inspired "Sound of Freedom," the new movie from Angel Studios that chronicles his work to rescue thousands of children from slavery and sex trafficking. The "only way" Ballard said he can deal with the dark and difficult work of rescuing children from sex slavery is "through Jesus." Throughout the conversation, he spoke about his personal convictions, his work with Operation Underground Railroad, and "Sound of Freedom," which earned a stunning $14 million in the box office on its opening day, July 4.
