If you've tuned into the past four seasons of A&E's show "Nightwatch," you'll definitely want to tune in for the debut of the newest show in the franchise, "Nightwatch Nation," which debuts Thursday, Aug. 16.

And you'll probably recognize some familiar emergency vehicles.

"Nightwatch Nation" is a series that takes viewers for a behind-the-scenes look at the busy overnight shifts of EMTs and the adrenaline-pumping environment of dispatch centers. It's like watching TV's "Cops" franchise with ambulances instead of police cars.

The show is set in Yonkers, New York; Austin, Texas; Baton Rouge, Louisiana; and Tucson.

"Nightwatch," debuted in 2015 and ran for four seasons. Each season was dedicated to a new city. This is the first time the show includes Tucson.

But the new show, "Nightwatch Nation," features multiple cities in one episode. Look for the Tucson Fire Department in all 10 episodes this season.

The first episode includes scenes of first responders in Tucson trying to avoid delivering a baby in the back of their ambulance.

"Nightwatch Nation" airs Thursdays on the A&E Channel.

Editor's note: The show is scheduled to air at 10 p.m. eastern time. Check your local TV listings to see what time your cable provider will be debuting the show.
