The trailer alone features several interviews of first responders telling their stories about how hard life has been in the wake of 9/11. Many are sick with lung problems and PTSD from their first-hand involvement with the tragedy. Others talk about the hundreds of thousands of dollars in medical expenses they have suffered as a result of being there on that fateful day. Yet others, many of whom have families to support, lament the fact that the after-effects have been so financially debilitating that they face losing their homes.
