"It's just really exciting, and just hearing all the stories of people who are going into this film pro-choice ... and are walking out pro-life," she said. "Every day I'm waking up to stories of people who are like, 'Your film changed my mind … I can't believe I ever supported abortion.'"

Listen to Johnson reveal amazing responses to the film as well as her quest to rescue workers who desperately want to exit the abortion industry:

Johnson said it has been "really incredible" to see the impact that "Unplanned" is having on the masses, explaining that the movie is truly sparking a collective movement.

"I feel like this movie is not just a movie. It really is sort of creating a movement," she said. "We want to get people plugged in. We want to rally around the people that are changing their minds."

Johnson is no stranger to changing hearts and minds. Her nonprofit, And Then There Were None, helps workers who are in the abortion industry find a way out. She herself was once a director of a Planned Parenthood clinic in Texas, before being asked to assist on an abortion. What she saw left her fleeing the organization and changing her views on abortion.

"We're actually reaching into these clinics and trying to get their workers out," Johnson said, noting that the organization sends mailers, calls clinics and trains pro-life advocates on sidewalks in how to appropriately reach out to abortion clinic workers.

So far, And Then There Were None has helped 500 people leave the abortion industry.

"We're trying to reach as many as we can, because we really believe that the majority of people who work in the clinics actually don't want to be there," Johnson said.

She knows from experience how hard it is to leave the job, as those who choose to do so lose their salary, friends, and other comforts.

"You're basically leaving everything behind," she said.

As for Johnson's own story, she went on a journey of healing after leaving Planned Parenthood. With an estimated 20,000 abortions unfolding at her clinic and another affiliated facility during her time there, she had to come to grips with her choices.

"It took practice. I realized early on after I left that I had a choice to make every single day that I woke up," she said. "That I could wake up and I could choose to live in my past — the place that I can't change, really the place that I feel like the enemy controls — or I can wake up and live in the present, I could live today for Christ in this gift that he's given me."
