Emmy Award winner Tina Fey (NBC's "Saturday Night Live," "Mean Girls") writes, executive-produces and stars as Liz Lemon in NBC's "30 Rock," a workplace comedy where the workplace exists behind-the-scenes of a live variety show. The show is told through the comedic voice of Fey and features Alec Baldwin ("The Aviator," "The Cooler" ) as Jack Donaghy, the brash new network executive who has turned the show upside down with his meddling ways.

The single Lemon is living every comedy writer's dream - head writer on a demanding, live TV program in New York City. Her life is jolted when Donaghy interferes with her show, and bullies Lemon into convincing Tracy Jordan (Tracy Morgan, "Saturday Night Live," "The Longest Yard") -- a wild and unpredictable movie star -- to join the cast. Now Lemon must manage the unmanageable so that the show -- and her dream -- can go on.

Also rounding out the cast in the half hour comedy are: Jane Krakowski ("Ally McBeal" as Jenna Maroney), Scott Adsit ("Kicking and Screaming" as Pete Hornberger,) the variety show's producer, Jack McBrayer ("Arrested Development" as Kenneth the Page,) the over-eager NBC Page -- a highly sought-after entry level position with the network, and Rachel Dratch ("Saturday Night Live" in multiple roles).

"30 Rock" is executive produced by Lorne Michaels.
