This drama focuses on the emergency personnel – police officers, firefighters, and paramedics – working in a fictional precinct and fire station who work the late night shift between three and eleven at night. These personnel refer to the area where they work as “Camelot,” due to the fact the police and fire stations were on the corner of King Blvd. and Arthur St. in New York City.

Originally the show was meant to only be about police officers and paramedics, but when Eddie Cibrian auditioned for the role of police officer Maurice “Bosco” Boscorelli, producers gave the role to Jason Wiles and added a part for Cibrian as a firefighter. Bosco can be quite cocky and isn’t one who enjoys taking orders. If there’s trouble out there, he makes it his job to find it. Bosco is somewhat of a lothario, bedding several different women throughout the show, but always has a platonic relationship with Faith Yokas, his best friend and partner.
