This was a special non-fiction episode which told, in their own words, the real stories of the police officers, firefighters, paramedics, emergency services personnel, and their families in the aftermath of 9/11/01. The regular starring cast members did brief introductions to each of this documentary's segments, which featured the real police officers, firefighters, paramedics, and emergency services personnel who work as part-time technical advisors and cast members in the production of every regular ""Third Watch"" episode.

It's September 21, 2001 and the squads continue to battle through their emotions and their misgivings about their hero status, while working double shifts and spending every free moment at "the pile" searching for the missing; Kim returns to work and teams up with Doc, which allows an emotionally frayed Alex to return to paramedic duty; an exhausted Sully attempts to co-exist with his prospective in-laws while he waits for an opportunity to marry Tatiana.
