American Morning (2021)

Two years ago, Connor Mathis (Stephen Dexter), a young elementary school music teacher, survived the seemingly unimaginable. A lone gunman forced his way into the school where Connor worked and opened fire. While this massacre was unfolding, Connor was forced to make a choice. A choice that saved the lives of all the children in his class, except one. The film takes place in the present where Connor has since quit teaching and moved back in with his father, Dale (Emmy-winner Richard Schiff). Haunted by nightmares and memories of that horrific day and enraged by the gross inaction of his country's elected officials to prevent this tragedy from happening again, Connor decides to take matters into his own hands.
