Season 5 of the sitcom, which takes place backstage at a network sketch-comedy series, is accented by an episode that, as its “The Live Show” title suggests, was broadcast live on both the East and West coasts. Story arcs include head writer Liz (Tina Fey) flying through some turbulence in her relationship with airline pilot Carol (Matt Damon), whom she met at the end of Season 4; and Jack (Alec Baldwin) struggling with the responsibilities that come from being a new husband and expectant father.
