The show-biz comedy’s triumphant Season 3 finale brings the legendary comic Deborah Vance (Emmy winner
Jean Smart
) to a new career pinnacle, with the prospect of hosting a late-night show. But will she be able to keep her conflicted protegee and comedy writer Ava (
Hannah Einbinder
) on board? Few shows depict the bitter realities of show business with as much flair, and only one thing can be counted on, in the words of Deborah’s estranged sister (J. Smith-Cameron): “The show isn’t going to make dealing with you any easier, is it?” TV legend
Hal Linden
(
Barney Miller
) makes a memorable appearance as an iconic TV exec with sage advice for the comeback queen.
