1) “Elsbeth” season-finale, 9 p.m., CBS. It’s a real stretch to plunk Elsbeth into prison, alongside eight people she helped convict. But it’s worth it, to see them again. Several are good singers (Gina Gershon, Retta, Alyssa Milano (shown here), Elizabeth Lail), so there’s even a dream scene of a song from “Chicago.” And there’s a clever, in-prison murder mystery.
2) “Poker Face” season-opener, Peacock. One of TV’s best shows is back, starting with three great hours. The first two — Cynthia Erivo in multiple roles, Giancarlo Esposito running a funeral home — have a long prelude and murder, then flash back to the arrival of Charlie (Natasha Lyonne). The third has her from the start, in a game-changing delight.
3) Academy of Country Music awards, 8 p.m. ET, Amazon Prime. For its 60th show, the ACM has a 12-minute opening medley of past song-of-the-year winners, performed by Reba McEntire (the host), Clint Black, Wynonna Judd, LeAnn Rimes, Sugarland and Dan + Shay. There are also performances by Blake Shelton, Kelsea Ballerini, Alan Jackson, many more.
4) “Grey’s Anatomy,” 10 p.m., ABC. Jo has seen some tough times. Her first husband was abusive; he died before they finished their divorce. Her second (Alex) was a good guy who left her for his ex-wife. Now she tries again. A week before the season-finale, it’s her wedding day with Link.
5) “Ghosts” season-finale, 8:30, CBS. The launch of Sam’s book is darkened by the return of two ghosts, Patience and Elias. CBS starts the night at 8 with “Georgie & Mandy’s First Marriage” (Mother’s Day gets tangled) and ends it at 10 with Alan Ruck playing feuding twins in an “Elsbeth” rerun.
