Toni Braxton movie on DeKalb school shooting scare debuts this week

Acclaimed singer-songwriter Toni Braxton is starring in a Lifetime movie debuting this week about the 2013 shooting scare at McNair Discovery Learning Academy.

The film, called "Faith Under Fire: The Antionette Tuff Story," will debut Saturday at 8 p.m. It's based on the book, "Prepared for a Purpose: The Inspiring True Story of How One Woman Saved an Atlanta School Under Siege."

Antionette Tuff, a bookkeeper credited with talking down the gunman before he could harm anyone, co-wrote the book.

Tuff, played by Braxton, was at work in the front office of McNair on Aug. 20, 2013, when Michael Brandon Hill, 20, came into the school with a rifle.

Thanks to Tuff’s efforts to talk him into surrendering, no one was hurt.

A short film about the ordeal is also up for an Oscar.
