Sirens is an American comedy television series loosely based on the British series of the same name. The American version was adapted by actor Denis Leary and screenwriter Bob Fisher.^[1][2] The series aired for two seasons on the USA cable television network from March 6, 2014, through April 14, 2015. On April 22, 2015, USA cancelled Sirens after two seasons.^[3]

The series follows the workday of three Emergency Medical Technicians with a fictional Chicago private ambulance company, named Eminent, and the unusual situations—often crude or humorous—people in need of their assistance are in.

In June 2011, it was announced that Denis Leary and Bob Fisher were developing an adaptation of the 2011 British comedy-drama Sirens, created by Brian Fillis and inspired by Tom Reynolds's book, Blood, Sweat & Tea about the London Ambulance Service. Leary stated that he would not star in the series, but would take a small role, if necessary, in the future.^[1] In 2012, the USA Network sought to rush the developing Sirens to pilot status. However, a deal with Fox Television Studios was carefully being studied over VOD rights. The network was able to order a series pilot in June 2012.^[5]

The four lead roles were filled in October 2012, with the casting of Michael Mosley, Kevin Daniels, Kevin Bigley and Jessica McNamee. Production for the pilot began in Chicago that month.^[6] The network announced that Sirens would premiere in the first quarter of 2014 and would later state that two back-to-back episodes would air together on March 6, 2014, then resume normal programming the following week.^[7][8]

At the January 2014 TCA conference, Leary and Fisher stated that the producers of the British series approached Leary's business partner, Jim Serpico, and asked him to adapt it for the U.S.. Leary stated, "We really liked those guys, and USA [network] was pillaging the cast of [the recently ended] Rescue Me and putting them into shows." He added, "we can make some money off these USA people."^[9]

On June 11, 2014, USA ordered a 13-episode second season of Sirens.^[10]

Sirens scored 61 out of 100 on Metacritic based on 19 "generally favorable" reviews.^[31] On another review aggregator site, Rotten Tomatoes, it holds a 73% rating with an average rating of 6.3 out of 10, based on 22 reviews.^[32]
