One and a half million American children have no fixed home, and the Panorama team sets out across the United States to find where they sleep. In Las Vegas that means storm drains under the strip; elsewhere it means tent cities that have become permanent fixtures on the edges of cities. Interviews with school officials and students trace what hunger does to a classroom, with one in six American children facing food insecurity and teachers describing kids who cannot concentrate because they haven't eaten. The film pulls in the numbers on race too: people of color make up 30 percent of the population but 40 percent of those living in poverty, a gap the reporters connect to housing policy, wage stagnation, and unequal access to schools and jobs. Running underneath the case studies is a blunter question the reporters keep returning to, about what happened to the promises made under Barack Obama's presidency and why the wealthiest country in the world still has children living in drainage tunnels.
