1) “The Voice” finale, 8-10 p.m., NBC. At the end of the night, the show will have its 20th champion. First, however, come lots of guest performances. That includes Blake Shelton’s fiancee (Gwen Stefani, with Saweetie) and his former “Voice” colleague (Adam Levine, shown here). Also performing: Justin Bieber, Thomas Rhett, OneRepublic, Kelsea Ballerini, Snoop Dogg, Ben Platt, Lauren Daigle.
2) “NCIS” season-finale, 8 p.m., CBS. Mark Harmon (who stars as Gibbs) is joined by his real-life wife, Pam Dawber. She plays a reporter and they’re linking to track an arms dealer. That leads a huge night for season-finales, including – at 8 p.m., Fox’s “Game of Talents” … at 9 and 10, CBS’ “FBI” and “FBI: Most Wanted” … and at 10, a big one: NBC’s “This Is Us” end its season with the wedding of Kevin and Madison – if all goes well. Last week, we saw signs of Kevin’s doubts.
3) “Mr. Inbetween” season-opener, 10 and 10:30 p.m., FX. With all those finales, we also need to see some summer shows debut. There’s the “Mental Samurai” game show (9 p.m., Fox) and there’s this intriguing oddity, starting its final season with two episodes. They ripple with violence and brutality, then switch to droll – and, at times, quite funny – understatement, as an Australian hitman navigates life with his 12-year-old daughter. The hour reruns at 11 p.m., midnight and 1 a.m.
4) “Mike Tyson: The Knockout,” 8-10 p.m., ABC. For a time, Tyson dominated boxing. In 12 of his first 19 fights, he had first-round knockouts. He was the youngest heavyweight champion ever, needed just 91 seconds to beat Michael Spinks … and then crashed. Here’s the first half of a four-hour documentary that concludes next week with Tyson’s rape conviction and his comeback.
5) George Floyd reflections. It was a year ago today that Floyd was killed; now TV looks at the past and future. At 8 p.m., BET has “Bars and Ballads for George Floyd.” At 10, PBS has “Race Matters: America After George Floyd.” Also at 10, ABC brings back its excellent “Soul of a Nation” series, for a special: Tamron Hall and T.J. Holmes host an hour that includes Floyd’s family, lawyer, pastor and more; it also has Aloe Blacc (singing “Other Side”) and poet Terrance Hayes.
