1) “Burden of Truth” season-opener, 8 p.m., CW. For summertime, the old “Supergirl” slot goes to … well, to the former Lana Lang. That’s the role Kristin Kreuk had in “Smallville”; she went on to “Beauty and the Beast” and then to this role as a tough lawyer. In the first season (shown here) she and Billy (Peter Mooney) won millions for teens in her old home town. Now she’s in a big city, Billy isn’t … and neither is happy. There’s potential, but Kreuk pushes her stern facade to a stony extreme.
2) Basketball, 8 p.m. ET, ABC, with preview at 7:30 and Jimmy Kimmel at 7. As the Golden State Warriors go for their fourth title in five years, they’re facing a tough hurdle. The Toronto Raptors – who had never been in the finals — won the opener, 118-109; they again have the home court for this second game in the best-of-seven series.
3) “Luther,” 8-9:30 p.m., BBC America. It’s been more than three years since this intense series had its fourth season … which was only two episodes long. Now we have a new one – with four episodes, no less. Luther (Idris Elba) has a new assistant (Wunmi Mosaku) as he probes seemingly random murders.
4) “When Calls the Heart” season-finale, 9 p.m., Hallmark. It was a hectic year for this feel-good drama. When the college admissions scandal broke, the show disappeared for seven weeks; editors eliminated Lori Loughlin and trimmed the season from 10 episodes to nine. Now Henry Gowen, once the evil mine manager, may get fresh power; also, the entire town schemes for a surprise.
5) Much more: NBC reruns the openers of “American Ninja Warrior” and “America’s Got Talent,” at 7 and 9 p.m.; HBO reruns its long-awaited “Deadwood: The Movie” at 9. But for something new – and compelling – catch the debut of FX’s “The Weekly” at 10 p.m., repeating a 10:30. Each episode is based on an intense New York Times investigation. The opener looks at a Louisiana school that gets its students into top colleges – partly, we’re told, by falsifying their transcripts and essays.
