Liz Lemon, played by Saturday Night Live's Tina Fey, is the head writer of The Girlie Show. When her old boss dies and a new boss comes in (Alec Baldwin as Jack Donaghy), demanding the addition of a volatile former movie star (and re-branding the show TGS with Tracy Jordan in the process), Liz must figure out how to keep things running smoothly without losing her mind.
