Ultra: The School for Young Assassins

When Chief Executives of the top secret agency "Ultra" get ordered to "prejudicially retire" the classified program for training child assassins to do the government's dirty work worldwide, they naturally comply by destroying the secluded Ultra Training Facility and terminating every last student, instructor, and staff member -- right down to cooks and janitors. But what will "Ultra" do about the rogue teacher and the six young assassins who managed to get away? BATTLE ROYALE-esque. Dark and violent.
