The series followed the exploits of a group of police officers, firefighters, and paramedics in the fictional 55th Precinct and Fire Station 55 whose shifts fell between 3 p.m. and 11 p.m, the "third watch." The precinct and fire station were located on the corner of King Blvd and Arthur St.; hence the nickname "Camelot." Exterior shots of the 55th Precinct and the Firehouse were filmed in Long Island City, Queens. Third Watch succeeded in presenting all three branches of New York City's emergency services in the same show, reviving a failed attempt to do so nine years prior with the similarly-themed H.E.L.P. running for only one season in 1990. The show balanced numerous single-episode events with other, ongoing storylines, some of which spanned multiple seasons.
