It's nineteen years after the Battle of Hogwarts and the Wizarding World seems to be back up and running. There are new employees in the school and in the ministry and the losses of family and friends hurt a bit less. The Golden Trio and their old schoolmates now have children of their own attending Hogwarts where they will stir up as much trouble as their parents, if not more, as the staff tries (emphasis in tries) to reign them in.
