Seven time Grammy® Award winner Toni Braxton stars as Antoinette Tuff, a struggling single mom from Georgia who heroically averted a tragedy, saving hundreds of lives when she convinced a deranged gunman who stormed an elementary school to surrender. On August 20, 2013, shortly after arriving to work at the Ronald E. McNair Discovery Learning Academy in Decatur, Georgia, Antoinette the school’s bookkeeper, was in the front office when Michael Hill (Trevor Morgan, "Abducted"), a young man with a history of mental illness, snuck in, armed with an AK-47 and hundreds of rounds of ammunition. As the school went into lockdown, Antoinette was left alone with Michael, who repeatedly threatened to kill everyone. Showing enormous courage and empathy, along with nerves of steel, Antoinette convinced Michael to surrender by using her own life struggles to connect with him. Antoinette’s faith in God guided her through the toughest moments of her life, ultimately preparing her for that fateful day. The film also stars Yaya DaCosta ("Whitney") as 911 operator Kendra McCray and Malik Yoba ("Empire") as Sergeant Franklin. Antoinette Tuff’s son Derrick, who was diagnosed with Charcot-Marie-Tooth disease, is portrayed in the film by Shalaby Omar ("Doubt"), a young actor with Spina Bifida.
