The comedy is at its peak and the storyline is better than ever on Season 4 of Hacks. The Emmy-winning show picks up directly after Season 3’s epic finale when comedy writer Ava (Hannah Einbinder) blackmailed her boss, comedy legend Deborah Vance (Jean Smart), into hiring her as head writer for Vance’s new late-night talk show. That big twist sent the comedy, which had already been outstanding on all fronts, into new territory, tossing Deborah and Ava into one hot and messy scenario in Hacks Season 4.
