 Jean Smart plays Deborah Vance, a comedy legend in Vegas who has spent years building a fabulous career, but whose stardom has started to fade. Facing the loss of her long-running casino residency, she reluctantly hires Ava, a young comedy writer who's recently been canceled over an ill-advised tweet. The idea is that Ava will freshen up Deborah's material, and at their first meeting at Deborah's palatial estate, they get off to a great start.
