The number in the title refers to a poll finding that 91 percent of Americans support expanded background checks on gun purchases, a consensus that has failed for years to become law. The film follows two intertwined tragedies: the deaths of sons and daughters killed by gun violence, and the political stalemate that keeps even broadly popular reforms from passing Congress. Interviews with grieving parents and survivors sit alongside conversations with lawmakers, lobbyists, and gun-rights advocates who explain why background-check bills keep stalling despite public support. The film traces how the gun lobby's influence in Washington outweighs opinion polls, and how grief has turned some victims' families into organizers and activists. Rather than arguing for a single policy fix, it lays out the gap between what Americans say they want and what their representatives actually do, using personal loss as the throughline that connects statehouse hearings, funerals, and campaign contributions.
