1) “Alert: Missing Persons Unit” finale, 8 and 9 p.m., Fox. After their son Keith vanished, Jason (Scott Caan, shown heree) and Nikki drifted. He struggled after returning from the military; she became a missing-persons cop and is engaged to a colleague. In the opener, they found a teen who seems to be Keith. Now these episodes wrap that up, alongside other cases. The two villains are way too similar and overwrought, but if “Alert” isn’t renewed, it’s had a strong finish.
2) “America’s Got Talent: All-Stars” finale, 8-10 p.m., NBC. This started with 60 acts that had done well in 19 different “got talent” shows worldiwde. Now the finalists compete for a $500,000 prize. There are six acts from the American edition and two from the British one, plus one apiece from Romania, Ukraine (Light Balance Kids, who then were finalists in the U.S.) and the Philippines.
3) “Bob (Hearts) Abishola,” 8 p.m., CBS. Bob’s ambitious plan, bringing sock-production back to Detroit, creates problems. Now he and Abishola rarely see each other; and Goodwin, taking Bob’s old job as president, is causing trouble for Kofo.
4) “Quantum Leap,” 10 p.m., NBC. Each week, Ben leaps into a different life, usually one that he feels lost in. This time, however, there’s a personal touch: He leaps into an Indian family, hoping to prevent its restaurant from burning down. Then a fondness for the matriarch stirs memories of his own family.
5) “The Madame Blanc Mysteries,” www.acorn.tv. Today’s first hour involves a murder in a grand house, just as Jean’s friends are busy buying it. The second finds an old friend feeling that he’s been cursed. That second one is simultaneously clever and an extreme stretch of logic. Still, each episode gives us pleasant characters in sunny settings in small-town France.
