Michael Mosley, Kevin Daniels Michael Mosley, Kevin Daniels

Pan Am alum Michael Mosley and Modern Family recurring player Kevin Daniels have been cast in Denis Leary's half-hour comedy pilot for USA, the network announced Thursday.

Sirens follows three of Chicago's top EMTs whose occasionally self-loathing, sometimes narcissistic and constantly self-destructive personalities make them poor choices for relationships, friendships and most careers. However, they are great at saving lives.

Mosley will star as Johnny, an attractive, sports-loving EMT who works with his best friend Hank (Daniels). The Vow's Jessica McNamee will play Theresa, a gorgeous and intelligent Chicago cop who still holds a candle for her ex, Johnny, but had to move on when he couldn't commit. Rounding out the cast is Kevin Bigley (Game Change), a wide-eyed and enthusiastic new EMT who still lives at home with his parents and is willing to take on whatever tasks Jonny and Hank give him.

Leary will co-write with Bob Fisher (Wedding Crashers) and both will executive-produce the project with Rescue Me's Jim Serpico, Hal Vogel and David Aukin. Victor Nelli (Happy Endings) will also executive-produce and direct the pilot, set to shoot in Chicago later this month.

Sirens marks one of USA's first half-hour projects. Leary and Serpico are also producing a comedy for their old network, FX, titled Bronx Warrants.

Mosley, who also appeared as Avery's co-captor on 30 Rock last season, will next recur on Last Resort. Daniels recurs on Modern Family as Cam and Mitch's friend Longinus.
