Third Watch is an American crime drama series which first aired on NBC from 1999 to 2005 for a total of 132 episodes, broadcast in 6 seasons of 22 episodes each.
The show was set and filmed in New York City, and with an ensemble cast of characters the storylines centered on the lives of police officers of the New York City Police Department (NYPD) and the firefighters and paramedics of the New York City Fire Department (FDNY), all working the same fictional precinct during the 3pm to 11pm shift - the 'Third Watch'.
After the September 11 terrorist attacks hit New York in 2001, season 3 opened with the award-winning October 15, 2001, episode "In Their Own Words", featuring interviews with real-life NYPD and FDNY members who responded to the attacks. The following episode was titled "September Tenth".
In the series finale, "Goodbye to Camelot", broadcast on May 6, 2005, the third watch is disbanded after a grenade attack burned down the police station.
