1) “The Bachelorette,” 8 p.m., ABC. Life is much easier for the guys who gets one-on-one dates with Hannah Brown: One gets a mini-concert by country star Jake Owen; the other strolls around Boston, drinks in the “Cheers” bar … and plays basketball with two Celtics (Jaylen Brown and Terry Roszier) in their arena. The other guys? They have a rugby game (shown here) that sends one to the hospital.
2) Hockey, 8 p.m ET, NBC. After giving a couple games to its sports channel, NBC takes over. This game – the fourth in a best-of-seven series – is in St. Louis; Thursday’s game will be in Boston.
3) “The Code,” 9 p.m., CBS. This military-courtroom drama won’t be back next season, but it has five new episodes to show. Tonight, lawyers fly to Afghanistan, where a Marine has been accused of killing an Afghan commander. Also, the colonel (Dana Delany) and her husband disagree about physical therapy for their son, who was wounded in action.
4) “Chernobyl” finale, 9 p.m., HBO. This chilling tale began with a deadly disaster and ends with a different sort of crisis – scientists trying to tell the truth, when their Soviet leaders don’t want them to. Ulana (Emily Watson) is a composite character, but Valery (Jared Harris) was a real-life scientist.
5) Games or cakes, 10 p.m. Take your pick: ABC has Kardashians, in a “Celebrity Family Feud” rerun; the Food Network has the season-opener of “Wedding Cake Championship” … which reruns its first season from 4-8 p.m. Both have quirky hosts – Steve Harvey on ABC, Tara Lipinski and Johnny Weir (the former figure-skating Olympians) on Food.
