Liz Lemon (Tina Fey), Jack Donaghy (Alec Baldwin), Tracy Jordan (Tracy Morgan) and the rest of the "TGS" crew return for a third season of this Emmy- and Golden Globe-winning series inspired by Fey's stint as head writer on "Saturday Night Live." With Jack taking a new job at Homeland Security, Liz's decision to have a baby and Tracy's high jinks continuing nonstop, there's no telling what's in store for the gang at 30 Rockefeller Plaza.
